Magnet Shielding

[riverstrat]

The problem that I've found with shielding is that magnets are just as attracted to the shielding as other metal ,it is ferrous (the shielding), if you could find non ferrous shielding you would have

something , otherwise the shielding is useless.

I'd appreciate someone proving that wrong, or developing non ferrous shielding.

[johnnytheprick]

@riverstrat

arent we ALL after the holy grail? do you realise how many magentic motors would be developed? it would ultimately end the fuel monopoly. its out there, but noones sharing it.

[Josh40996]

Interesting, have you tried making a magnetic motor from this? Or do you not have any MU metal available?

[Stopgangstalking2011]

There are electromagnetic fields such as cellphone towers that can be unhealthy for people to be around. Is it possible this material could be used to block harmful electromagnetics if it was built on a larger scale? Where would someone want to go about it. Get a slab of nu metal and a magnetic and mess around with it until the other side of the nu metal is not magnetized?

[harveyeaston]

lol, the screwdrivers and computer blankoff plate were magnetized... so they only looked like they were not attracted on the matching polarity; notice how everything jumps away on the back side of the plate?

[FreeGlobalEnergy]

@harveyeaston

There are no tricks here. Had the screw driver, the screw and the blankoff plate been magnetized they would have stuck to the metal plate and not pushed away. The metal plate is sitting at an angle which is why things are falling off of them the way they do. I am not a trickster. I was amazed at what I found here and thought it could be of some use for an inventive mind. Find a throw away HD, open it, take out the parts & see for yourself.

[unix001]

@harveyeaston -.- ur retarded.

[xptos1]

I'm thinking that molybdenum and silver could have interesting results

[kazukan2kgmail]

stainless steel..

[MrHyburn]

dude, come on. its a neodymium magnet+nickel plate=0 magnetic transfer.

neodymium*5+Nickel plate=5 which is a higher level of magnetic transfer.

its simple math, if you increase the amount of magnetism, you get more on the other side. in its original state, the nickel is enough to counter act the magnet.

[gauravminocha1]

hey

Can you tel me where i can find mu metal leaving the old hard drives that are not easily availble?

Also it would be great if you can suggest me the places or products in which i can get MU metal thin small sheets

[GlobalAwareness2525]

@gauravminocha1

You might try: Magnetic-Shield (dot) com

youtube doesn't allow web links here in the posts, so if you don't understand what I did above and can't get to that link then please ask me for help.

You can also Google the words: mu metal sales

[tomek123kotek]

those some are right... if you get the strongest magnet on earth... there is no way to shield it other than to enclose it... that magnet is just not powerful enough but if you had a more acurate way of measuring you would find there is still a small magnetic pull

[LOLDISNEYLAND]

It doesn't shield a magnetic field, it diverts the field and makes the field strength very weak because the lines of force have been concentrated in the metal. It's very simple.

[fuelban]

hi guy, if you check out ......... FuelBan & Magnet Motors 1.wmv ........ videos 1 to 3, you can get an idea how to manipulate steel to suite rotation. But this is not shielding .

Thom in Scotland.

[grifflesnaffle]

The metal in the video is call Mu-metal. Mu-metal is a nickel-iron alloy (approximately 75% nickel, 15% iron, plus copper and molybdenum) that has very high magnetic permeability,which makes mu-metal very effective at screening static or low-frequency magnetic fields.

Magnetic shielding made with high permeability alloys like mu-metal works not by blocking magnetic fields but by shunting them—providing a path for the magnetic field lines around the shielded area

[neelespn]

I'm busy to build a remote robot.

with a magnet generator, for electric power. instead of a battery pack .

I'm already putting out 300 watt of electric power.

the video is coming soon

[GenevaSuspension]

It only warps the magnetic field, it doesn't block it. That's why on the MU metal side, when you've let go of an object, it gets repulse right off the table.

[FreeGlobalEnergy]

Yea it does look like some mysterious force dragged or pushed it off the table but I assure you that is not the case. it just fell off when I let go and just happened to slide off of the slippery table.

[fuelban]

@GenevaSuspension The curved magnet has a double pole, no good to use in motor, and the metal {shielding} we see here, wont work either im sad to say, if you get a plain round magnet, cover half it with the metal shown, then try to pass another magnet over it, that magnet will be attracted to the metal, try it.

[ashish19]

Very nice video, and a nice demonstration of how the materials with high permiability can be used to shield magnetic fields. Thanks.

[ales024]

great video

I get a lot of info here inside this video

tnx

[MRJOSEPHKING1971]

hey FGE great site

this metal is a cheap pot metal

with crome allowing the mags to sick

and nothing going all the through

as far as iron yes im guessing

im on 5 hrs of your vids so far

im thinking of converting my fiat to water

[milolouis]

i dont know if anyone has said this yet but actually both the poles to this magnet are on the top side thus creating a zone of no discernible magnetic force on the opposite side but LET ME ASSURE YOU this is not mu-metal and this does not block the magnetic field it is JUST the shape of the magnet.

[FreeGlobalEnergy]

Wrong.

Later I pried off the magnet from the metal and both sides were magnetic, not just the top but the bottom part as well and yes, each end were opposite poles but not only on the top surface.

You should be able to find someone with a stack of old hard drives where they will give you one for free then you can tear into it and see for yourself

[mespe79]

@FreeGlobalEnergy

it's ordinary steel. with the N pole on one side of the metal and the S pole (of the other magnet - you see the one magnet is actually two magnets) on the other, the metal carries the magnetic flux. Add magnets, and you will need a thicker metal,,,

[FreeGlobalEnergy]

The magnet is North & South on each end as you say. When I pried the magnet off of the metal then the magnet is magnetic on both sides.

If the part of the magnet that touches the metal plate is magnetic & if the metal is steel then the steel plate would have become magnetized just like if you took a non magnetic screw driver then left a strong magnet on the screw driver then the screw driver becomes magnetized able to pick up screws. I do not believe this metal is steel as it was not magnetized

[FreeGlobalEnergy]

The odd thing about this metal is that it behaves like steel where magnets cling to it but does not become magnetized like steel

[mrwiggles123123]

@milolouis wrong.........took the magnet off and stuck another Neodymium Magnet on ....it same affect

[johnnytheprick]

FREEGLOBALENERGY,

yes, but does it sheild from other magnets?

[FreeGlobalEnergy]

That is a good point and now I see the problem in considering this as useful because It really doesn't matter if it blocks or doesn't block magnetic fields. The big problem is that it IS metal. Any magnet rotating near it will lock only because the plate is metal. I saw other magnet shielding videos that used dead batteries where he demonstrates it as successful in eliminating the locking of rotation or the sticky points.

[johnnytheprick]

FREEGLOBALENERGY,

ive seen it and its cumbersome. all i need is a material thats at least 1mm thick but it has 2 be able 2 sheild 100%......but ill settle 4 90%.

[FreeGlobalEnergy]

Johnny:

This isn't something I have been pursuing. What I discovered above was by pure accident but if I wanted to experiment with the battery idea & I needed it to be thinner I would open up the battery & see if somehow I could smash the contents flat then maybe squirt glue all over it, let it dry then cut sheets of it. If you do something like this & it works I would be interested.

Please post a video reply if that turns out to be useful

[johnnytheprick]

FREEGLOBALENERGY,

atm, i live in a 1 bedroom flat, in effect, its a bit hard 2 make any noise so i cant just "smash" open stuff.

ive never posted a vid on youtube, and wen i do, i dont think ill stop.

i think my 1st will b a instructional guide on doing the 3x3 rubiks cube, followed by "online dating", sudoku, homemade cnc machine, and but but not least, an "almost" perteptual motion machine. i say almost because it has been said magnets only have a life of 400 years.  ;-)>

[nitschke22]

no this shouldn't matter because the energy lost in getting away from the metal would have been gained on the way in, plus if its set up right you should be getting net gains off of the magnetic force of what is essetially a monopole magnet.

[prototype9000]

i found a website about magnetic shielding one of the matierials was called giron and nickle alloys will shield magnetic fields dont believe everything books and school tells you usually they are loaded with disinformation and insult to america for making us look do dumb

[joelbernarte]

What is the name of that metal on the back of the magnet?

I think the metal on the side where the magnet sticks, is a magnetic metal, while on the other side, is not magnetic.

What is that metal? Anybody please tell me! Thanks!

[FreeGlobalEnergy]

Somebody in these posts says it's MU Metal, I have no idea if it is true or not but keep searching Magnetic Shielding, one guy uses dead batteries with amazing results & I tell u what, Science can ignore this all they want due to government pressure, I just know that magnet motors do exist & all is covered up so I encourage all to never stop with their experiments.

[abhimanyu5]

the only thing that can protect an electronic item from an EMP blast is a thick casing of mu metal. but the casing has to be thick otherwise it wont be able to stop the magnetic pulse.

[abelenda76]

Hola solo quiero comentar que es de acero dulce y que al ser inducido por un campo magnetico se imanta y ya no sirve como blindaje saludos

[suupertramp]

i swear that th magnetic field lines go through the metal sheet instead of the airbecause it is easier...so if it does not go through the air, then it cannot pick up something. however, not all of the field lines will go through; some go into the air, and as you proved with stronger magnets, more will go into the air. did you experiment with other magnetic materials to see if the effect was the same?

[FreeGlobalEnergy]

I did not experiment with any other types of metal as a slot protector on the back of a computer is as metal as anything other kind of metal you may have lying around the house

[DionMarinos]

Very kool man.

thanx for sharing this.

[raven222002]

thank you very much for bringing us that . RSW

[JordanMaster22]

this is the thing that make permanent magnet motors possible

[Zedkazar]

it is the MU-METAL?

[FreeGlobalEnergy]

Some people say it is, I don't know. Beyond this is something I think is far better, keep searching magnet or magnetic shielding and there is a guy who is using dead alkaline batteries as shielding. He wraps batteries around magnets and this removes the dead spot you get when trying to propel a wheel, the wheel attracts where it should then propels when it should with no dragging or pulling but propels the magnets on the wheel forward.

[TechnicalFreak]

Want a strong magnet? Take the "motor magnet" of an FDD. That's powerful.. So powerful, I put one on our garbage room door, and they had problems removing it!

Also the HDD's "electric engine" can be used in RC cars (installed correctly) and can give you speeds up to 70Km/H..

[kdkinen]

so is there ony one polarity, or do both share the same side now??

[datlildodge]

lemme tell you somtin:

when they make magnet motor, it will have nothing to do with sheilding

[earthga]

I don't see the point of shielding?

Either you have to move magnet or shield at the right time(and lose energy).

PS: Stronger magnet to shield, heavier shield you will need!

[krazeekooladam]

steel is a useless shield. a magnet on the other side will attract to the steel. You want no attraction or push on the other side, so steel won't work.

[madepandora24]

very interesting video

[flashguru1970]

hi... have you ever been thinking about shieling whith the "halbach array" and the right hohly geometry??????

thx and greetz

flashguru

[addadhdnarc]

The way this works is on one side of that curve u have the magnetism pulling and the other pushing away. add electricity, and the disk inside spins. The disk is coated with iron oxide or is iron oxide, not sure. I used to hear my hard drives spin randomly when my computer was off. This is old technology. One of the 1st hard drives that looked like the ones now was about 50x's the size. those magnets were much more powerful, i'm sure. thanks for posting, i was to lazy to do so.

[Careica]

Bullshit! It is pulling all stuff away! Nice try.

[FreeGlobalEnergy]

¨Its pulling stuff away¨

What the fuck are you talking about

[reallybigname]

yeah, what the hell?

[futahroid]

Wikipedia "Mu Metal"

Quotes:

Mu-metal is a nickel-iron alloy (75% nickel, 15% iron, plus copper and molybdenum) that has very high magnetic permeability. Permeability is represented by μ.

The high permeability makes mu-metal very effective at screening static or low-frequency magnetic fields, which cannot be attenuated by other methods.

Mu-metal is used to shield equipment from magnetic fields.

Hard Drives, which have mu-metal backings to the magnets found in the drive.

Unquote

[2550osiosterdalen]

I have tried those magnets and it seems that they have both south and north poles at the same side. So it mught be the reason that the magnet only attracts the metal at one side.

[FreeGlobalEnergy]

I pried that flat magnet off of the plate.

It does have magnetism on both sides but one end is South & the other end is North.

This magnet is not like an ordinary magnet where N is one side flip it over & the other is S, but N&S are at opposite ends instead of opposite sides. Normal metal sticks to every part of this magnet end to end & both sides

[cipriuss]

You are right about the poles of the magnet.The magic plate is not mu-metal, its just a simple ferromagnetic plate. the magnetic flux from the NORTH pole is searching its way home to the SOUTH pole, and since it cannot travel in straight line, it travels around the magnet like in a circular path, attracting small pieces of metal that this flux encounter .On the other side of the magnet, where is the metal plate, the flux travel from N to S via the metalic plate :D hope i am right

[ValensAetas]

I'm sorry but I disagree, it is simple polarity that you are experiencing. When you are putting the metal items next to the back of the "shield", you see how the screw and screw driver were thrust off of it, and fell off almost as if they were pushed. It is simple polarity for the non-magnetic metals that you are placing in contact with the underside of the magnet that is attached to the "shield".

[FreeGlobalEnergy]

Regardless of where you place a screw or piece of metal onto a magnet it pulls the screw to the magnet. Never does a piece of metal resist any part of a magnet, only another magnet will resist a magnet.

[PacVsEu]

LMAO the material is extremely dense which holds in the the field, the magnet does attract to the plate, but the plate absorbs the field, like how lead does it.

[futurisnow]

strange. Never seen a such material like that. It could be use for magnet motor.

[freudeface]

Ferromagnetic materials are influenced by magnetic fields, but only conduct magnetism if magnetised or in direct contact with a magnetised object. the reason the magnetic field is not conducted by the metal plate is because there must be a thin coat between it and the magnet. Also the metal plate must be of ferromagnetic material as well, otherwise it would not influence the field. try it. sheet iron, sheet paper, magnet all stuck together in order. On the iron side there will be no strong field

[spikeychops]

What are you saying here then mate?

"the reason the magnetic field is not conducted by the metal plate is because there must be a thin coat between it and the magnet" So are you saying the metal is NOT shielding the Flux or a thin (very thin!) coat (of something??!) is acting as a shield. Well, that begs the question, a thin coat of WHAT?

Of course it's the metal that's shielding the flux, i did the same thing with a hard drive, and got exactly the same result. Flux would NOT pass through

[freudeface]

its the metal thats shielding the flux yeah,,.. but that also means the metal shielding must be ferromagnetic material... mhich also means if the magnet was in direct touch with it, it would also turn it into a magnet.. innet :-)

(which means they must have used clear coating,

lack or so of some sort, maybe even just the glue

[freudeface]

no the thin coat is not the shield,, it just holds a space between the magnet and the ferromagnetic metal... if there was no space at all, the magnet would just turn (in this case the shielding) metal into a magnet .,

[helpmonkey]

(in Arnold Swartznager voice) Ah.. do'es are wimpy little magnets, if you want some real magnets get dem from da SCSI hard drive .. yah

[davesms8]

This material actually does the job for any solid-magnetized magnets. Of course it has a leakage, but the attraction on the shielded side is much less.

[waragainstgreed]

this is not shielding or blocking or any other effect in which magnetic fields are being stopped dead in their tracks... its either as Sasham4 posted already - being both poles are directed to the "front" of the piece in something of a crescent shape, OR its a series of magnets in a Halbach array in that patch of metal.

[helpmonkey]

it is not megnetic blocking ... it is called sheilding which simply provides a path for the megnetic field which compresses the megnetic field on the metal side.. if you can find a material that blocks megnetic fields... eureka... there has been some research into rotating megnetic fields and its effect on gravity... but most of these people end up talking to alians

[abilityoflove]

"most of these people end up talking to alians"

I don't see anyhting wrong in talking to aliens... LOL!

[farter8000]

we have had this technology so long and have used it without knowledge of the numerous divices that use/it all the while scientists and engineers struggle to find a way to make better technology/with the new tech such as the magnetic engine and magnetic generater implimenting this tech nology would make it so that these engines and motors would never interfere with other technilogical divices/why is fact hiden/why are many companys not using the magnetic engine or generator/other companys afraid

[maulerrw]

what are you on about?

[ysin98]

Great Vid! 5 stars.

[FreeTalkLive]

Take a hot air balloon. Mount a big ass magnet on the bottom of the basket and block one pole with this metal.

The balloon should be pulled to either the north pole or south pole of earth. This would be some cheap propulsion.

[Sasham4]

Explanation: There are two metal surfaces, the top one being magnetized. Just as it is demonstrated in the video, with N pole on right, and S on left (or vice versa), and the catch is, the direction of magnetization. The top metal (magnet) is magnetized so that both north and south pole come outward, towards the camera. When he adds more magnets, which are magnetized through the cylinder (N on one side, S on other), they create a magnetic field , much stronger, that overpowers the weak magnet.

[zesbreon]

if you wanted to remove the metal shielding just get the screw driver and place it on the magnet and use a hammer to break it off, i tried it and it works but some of the magnet areas can come off.

[Paxmax]

Adding magnets will saturate the metal strip and increase leakage, thats why things will stick to the backside.

Still even with just the original magnet you can detect leakage with something light like a needle.

BTW holding a needle(verticly) and moving it side to side above the middle of the magnet you will sense something funny. The needle does not want to be suspended between N and S pole, it will rather want to move to either pole. It will do it's best to short out the magnet.

[Paxmax]

Like I told you in the original vids comment section. It's not a "sheild" as in "it will deflect magnetism".

It will ATTRACT magnetism if it provides a shorter path between N and S pole.

Since the magnet is glued FLAT on the metal most of the magnetic force will be SHORT CIRCUITED through the metal.

Stop vid at 20sec, you'll have the magnetic poles on the left and right side of magnet.

If you insert this "sheild" between your cart and mag array the sticky spot will remain.

[Paxmax]

The carts magnet will attract the metal "sheild" and the sheild will also be attracted to the mag array.

There are a FEW metals and metal compounds that isolate magnetism a tiny tiny fraction more than vaccum. but still, it's too much of a fraction to even make a difference.

[jamesroney]

You went on to comment that because the magnet is so thin that it might account for why there is little to no attraction on the reverse side.

I went on to tell you that you need a spacer between the magnet and the shielding.

Funny how your video is nothing more than showing magnetic properties and my post on the same date gives you the answer via a blueprint how it's done, yet more people are more interested in watching someone tinker with magnetic parts. Go figure.

[jamesroney]

Why do you post this video as new.? You posted this same video back in 2007.

[picaxe]

who ever says its impossible?

[FreeGlobalEnergy]

To picaxe:

-"who ever says its impossible?"-

Every now and then on some of my other magnetic motor sites, namely the v-gate, when I suggest that magnetic sheilding could get rid of the sticky spots they would always say that is impossible, there is no such thing as magnetic sheilding, so I made this video, now they are dumb founded

[picaxe]

its just a nikcle and iron alloy (bit o nitrogen thrown in for a laugh), useful but still Mk1 standard physics, to be fair it is a random little material i doubt many have heard of

[FreeGlobalEnergy]

Some claim it is called MU metal

[Paxmax]

I don't think MU metal would be nescessary for this application (to stop magnetic flux leakage).

[Citdoitsmile]

there are simple ways to to turn lead into gold.....just do the math....it is simple addition actually. The equipment is not hard to make either. The downside is the cost per unit. Simply put for those not following this, it cost more in power to make the gold than the value of the gold.

[jesslessthemess]

oohhh...considering the availability of h2o, and therefore hho...we might be getting somewhere.

so what's the formula?

[Locris2007]

the magnet from the hard drive has mag shieding, the magnetised side has both neg and pos ,not sure which is which though will find out

[paypascal]

The only problem is magnets are attracted to the metal. So you could use it to shield the magnet but both sides do attract other magnets.

This is not useful.

[FreeGlobalEnergy]

Good point although click on the link under the video and see the comment from SuperNovaCain, he says

-"However I find myself almost stunned at finally seeing what's always been sitting in front of me. Back-to-back, they don't react almost at all."-

Don't be so quick to dismiss. many times it is the worthless crap you threw into a box that later becomes the answer to the puzzle in future projects.

[shubus]

See wikipedia on "Mu Metal" - warning when machined it substantially looses it's characteristics and needs to be re-annealed.  As a shield in a magnetic motor app, hysteresis eats up energy gain achieved thru the motor.

[Reverseflush]

Looks like a brake pad

[analyzingfunny]

The metal the frame is made of is not made of pure steel or iron. It is a mix of aluminium, zinc mabey maganese and iron.

Currently I am in college for physics and mabey metalurgy.

I would like to add that auto shredders use eddy current and a spinning aluminium cylinder to repel aluminium in order to separate it at high speeds.

The lead at Chernobyl turned to gold, the news in the inner circle said so.

Also watch "Tesla the Race to Zero point.

It talks about transmutation of metals.

[FreeGlobalEnergy]

"The lead at Chernobyl turned to Gold"

I have a book that I forgot about claiming that Gold can be created in a laboratory, your comment is the first I have heard of this since buying the book 13 yrs ago and has re-sparked my interest in this claim, I just need some College students with access to a Lab. In the book one process is Nuclear synthesis by thermal burn but using black sands not lead. I can't comprehend the book I need an Alchemist, 215 pages of math I have never seen before.

[analyzingfunny]

Watch "Tesla the Race to Zero Point" If you pay real close attention; scrutinizing type attention, it is really scary; but scientifically wonderful at the same time. The quivering metal, and levitation parts are fun; but the part about changing silver to rhodium, or spend uranium into something useful, is here and now, with high frequency. Watch the video; for the Christians, it is the Holy Spirit, for Buddist is the light of the third eye; it is the glowing ball they sell at Specer's gifts.

[closetpunk2006]

In a chemistry lecture last year the professor made an offhand comment about this. He was talking about the old alchemists who tried to turn lead into gold before we knew that it was impossible - but then quicky noted that it is in fact possible, but that it was "another story". Then he went about the normal lecture routine - but, he did acknowledge it.

[gun844]

use mercury!with enough energy you can make gold.But at high costs(in energy... this is why the scientist didn't use it.

[sn1pe352]

If some say that's really impossible then good job...although I don't personally think its impossible I do think it makes for a great discussion and may even lead to greater discoveries for those who do believe its impossible. gj

[gabydewilde]

Yes, flux can be blocked or more correctly guided though the metal from pole to pole.

I bet that if you place an extra magnet on both north AND south pole the flux wont come though again. Your theory is still correct if you put to much extra magnets on it of course.

View my flux switching video. It's basically about the same thing.

[spanishaustralian]

you are a fucking genius.
