Answer to the question "Can magnets be 'used up?'"

[Xero555000]

You are a very smart man... i just want to let you know that despite all of the dislikes that you get... i appreciate the work you have done... you have a great passion and i can see how much you dislike the ignorant being swindled... in engineering we say we are doing the impossible for the ungrateful.. i feel like you are doing something of the same thing :)

[XxxThePsyCheMisTxxX]

The hilarity of the lack of intellectual prowess of the perusers of this strange website amuses me. Moreover, go read a bloody physics book. I had to lecture about Einstein on another video because nobody read anything first (including the author of these vids). Save me - and yourselves - the trouble. Read. A Damn. Physics. Book.

[nikolayzou]

The universe is full of energy and only 5% is from atomic energy. Over unity may not exist, but you can create devices that extract energy from the vacuum. This guy talks as if he understands the whole universe, but he is only talking about 5% of the Universe. He is very rude and a bad dresser. And what's with that stupid hat.

I think the term over unity and free energy are bad terms, better to use vacuum energy.

[XxxThePsyCheMisTxxX]

@nikolayzou 5% of our universe seems to be baryonic matter and energy. The rest seems to be dark matter and dark energy. This claim is baseless and has nothing to do with vacuum energy, which is the notion that virtual particle/antiparticle pairs form and annihilate spontaneously all the time. A method to extract this energy has never been conceived on a realistic level, and so this effect is moot. Read. A. Physics. Book.

[nikolayzou]

@XxxThePsyCheMisTxxX They will be able to extract vacuum energy in the near future if they aren't doing it already. Physics books will have to be rewritten.

[Desertphile]

@nikolayzou ; No, "they" will not be "extracting vacuum energy" any time in the next few billion years. It's impossible.

[nikolayzou]

@Desertphile How do you think the Universe got here????

[Desertphile]

@nikolayzou ; "How do you think the Universe got here?"

The same way all of the scientists say it did.

[nikolayzou]

@Desertphile Well there is a major gap in our understanding of the Universe, so what scientist say isn't written in stone.

[24hosting]

I found an error. You say there is no such thing as free energy.Fact is ..It's all around you. .Every day of your life.If you can not find it. You just ignorant. Fact.

[Desertphile]

No, there is no such thing as "free energy."

[nickvhopwood]

@Desertphile you make me want to give up alcohol and take my life more seriously.

[Edelwulf]

LOL. Quoting from a science fiction book even if it's sound physics is tantamount to your insanity, whether perceived by self or not. And Herufaia, let's just tax Sol for being so wasteful!

[Desertphile]

Translation: you were unable to spot any error in my video, and that frustrated you to such an extent that the best you could do in reply was to try an insult. How very sad your worthless life must be.

[24hosting]

There is Free Energy all around you. How can you say it does not exist. Sun gives off free energy, wind is Free Energy,Magnets give off Free Energy. These are facts. Get it right.

[Desertphile]

No.

[XxxThePsyCheMisTxxX]

@24hosting Magnetism is a type of force, not energy. If you don't know the difference, I'm saddened. Read. A. Physics. Book. Dammit.

[XxxThePsyCheMisTxxX]

@Edelwulf quoting a science fiction novel about sound physics isn't tantamount (syn. equivalent, not what you were using it for) to insanity. In fact, not only did Asimov use a lot of real science in his fiction, but the specific effect being discussed here is how neodymium magnets are made. Some for further use in potential overunity devices, which is funny.

[gothicluke]

this may be a dumb question but as you are talking about magnets, is it true that if u drop a magnet it loses strength or is it just crap i was taught in school? lol

[Desertphile]

Giving a magnet a hard smack will thermally agitate the atoms and cause a weaker magnetic field: a hard impact is similar to heating a magnet.

[jonahdabona]

i don't under stand what the water supply has to do with the sun shine, im sure there is a limit to the energy the sun puts out but that is so beond our on existence here on this planet as of now and we need free energy so we don't completely destroy our ecosystem. ummmm yah lol

[Herufaia]

I have an idea of the "rediculous" amounts of energy a g2v type star such as sol puts out....compared to what we use yes it is alot of energy but there are ways to use even that kind of energy up.

Further more IT IS NOT FREE! You don't get it.

Even if the sun gives off all this energy and we would use but a fraction of it it is not fucking free.

The sun loses millions of tons of it's own mass every day just to give us that energy.

[jonahdabona]

the sun give free energy

[Desertphile]

"the sun give free energy"

No.

[jonahdabona]

if the sun makes plants grow, and i dont believe the plants have to pay for it. do they?

[lifeisfair123]

The sun makes energy by nuclear fusion of hydrogen and other elements intohigher elements. At some point in our universe's future, all suns will run out of energy and the universe will be cold. The energy is not free.

[jonahdabona]

but in the here now it still IS free energy, at least in the time being.

[lifeisfair123]

I guess if you want to define it as free in this way, you are right.

[AisuSeijin]

It's free just as much as the water supply is unlimited...

[Herufaia]

That will take a few trillion years but it will happen.

From what I remember I think an m9v red dwarf star ((the smallest kind of main sequence star)) has a lifetime of around one trillion years.

[24hosting]

But I will have it for my life time. There for it's free to me and you and everyone else. Don't go some place you will never be. Come on...

[lifeisfair123]

What about our ancestors if our species last this long? You have American syndrome. Me,me,me. Now,now,now. Guess what. If our species last very long, someone will have to confort this problem. I guess I hope for the future. You only think of now.

[lifeisfair123]

Ancestors is suppose to be descendants.

[keithpaz]

you can get free energy if the people that give it to you dont ask for money lol

[whitl103]

Hard to really get a solid point out of this video.

[FightingCreationist]

If someone proved free energy to be real, this guy would blow his brains out.

[Desertphile]

"If someone proved free energy to be real, this guy would blow his brains out."

If you mean me by "this guy," then the answer is "No, I would not."

"Free energy" is impossible.

[FightingCreationist]

Yes, you.

I'm going to have to develop a perpetual motion machine just to prove you wrong...

[Heathenfidel]

Makes perfect sense that a creationist would believe in free energy too. Like the moldy old book says, "With God all things are possible." Yep, you can do anything with God-magic.

[UFOMAN618]

You probably believe that the earths magnetic core is not powered by cosmic radiation either.

[unhealthytruthseeker]

If you want to get energy from a magnetic field, construct an RL circuit and allow the solenoid to fully magnetize. Then disconnect it from that set up and connect either end of the solenoid to the terminals of an electronic device. The energy stored in the magnetic field will power the object, but not permanently. As the energy goes into powering the object, the magnetic field in the solenoid weakens.

[RyuDarragh]

You can also damage a permanent magnet by moving it inside a shorted coil. This can heat the domains above their Tc and cause the loops to be broken. There are even devices, like some thermal/magnetic circuit breakers, that depend on this Tc (critical temperature) to operate. Ferromagnetism, paramagnetism, diamagnetism (love Bismuth or Pyrolytic Graphite :D) and nonmagnetism (the last being things like glass or air that are super weak paramagnetic materials).

[RyuDarragh]

Yep. Most particles carry an electric charge. The Electron being the definitive particle with an electric charge. Yhe proton has exactly the opposite polarity, but same value. The electrical field is a spatial twist on the *magnetic* field. The one begets the other. Since the current loop on the magnetic crystal face (the domains) is a superconductor, it can *transfer* current via the magnetic field to another conductor. Any loss is made up by the input energy. In effect, it's a *transformer*.

[spdelgado1976]

i´m sorry for the error !

a motor bedini with less than a 1 watt of power ( 12.5 volts * 0.065 amps ) can cause a rotation of a big bicicle well and charge 4 12 volt batteries ( four !!!!! )

remember less then one watt !!!!

[spdelgado1976]

can you explain me how motor bedini with an watt of input can pull a big bicicle well and recharge a 12 volt batterie ?

when we use a wind mill to power an generator we are taping energy from air ?

does air has energy ? can we develop another machines that colects energy from air ?

if you devolop a machine that colects energy from air are you violaiting the law of conservation of energy ?

[spdelgado1976]

dear desert

you are now with a big problem so you tell the magnet is a conversor that converts kinetic energy but you don´t pay to him for that job !!! ´

you are not a physics as you said in another videos !! so what are you ? an actor thas is being paid to teach ? are you a professor ?

can you explain what´s happens in perepiteia motor ? can you explain how bedini motor works ? why bedini motor recharges death batteries ? why Nicola Tesla said that radiant energy exists ?

[ScientistKeith]

I wanted to expound on what you said about kinetic energy and the weakening of permanent magnets.

In industrial power plants, the inefficiency of transforming motion into electricity via magnets also produces heat.

If the magnets heat up enough, then the atoms or ions can realign themselves enough to weaken or destroy the magnet. Note, it's the heat, not the production of electricity directly, doing this.

To counter this, power plants cool the magnets continually (usually with water).

[BlackDogSociety]

So the energy comes from the motion and not from the magnetic field, then why cant I get electricity from a coil by passing a piece of aluminum, wood, or any other non-magnetic item over it repeatedly? Since energy must come from somewhere then the magnetic field must weaken over time

[kmarinas86]

"So the energy comes from the motion and not from the magnetic field, then why cant I get electricity from a coil by passing a piece of aluminum, wood, or any other non-magnetic item over it repeatedly?"

Aluminum, wood, and other non-magnetic materials have very weak magnetic coupling with the external magnetic field, except if that field is so strong, like those around neutron stars.

"Since energy must come from somewhere then the magnetic field must weaken over time"

Can you explain that?

[BlackDogSociety]

Actually after thinking about it my statement is not correct. Electricity is produced by passing a coil of wire through a magnetic field, this field causes the electrons in the wire to move making a current in the wire. There is no transfer of energy from the magnetic field to the wire. So please disregard my statement

[ScientistKeith]

"Why cant I get electricity from a coil by passing a piece of aluminum, wood, or any other non-magnetic item over it repeatedly?"

You CAN and DO. However, since the magnetic fields are randomly distributed, instead of aligned, as in a permanent magnet, the positive and negative electrical fields produced CANCEL each other out, with a net result of negligible electrical current. Only in a permanent magnet are the fields aligned well enough to produce a net electrical field.

[BlackDogSociety]

ScientistKeith you contradict yourself, if the random magnetic fields cancel each other out then you dont get any electric current as I stated.

[ScientistKeith]

No contradiction.

First you said "electricity" not "net electric current", which I took to mean any form of electricity.

What you described can produce disturbances in the electric fields, which can create a voltage or "static electricity". However, the random distribution does prevent a useful amount of current from being obtained.

"Electricity" is a generic term. For these discussions we need to use more precise terms like voltage and current, to prevent miscommunication.

[BlackDogSociety]

ScientistKeith, Im also sorry you misunderstood what I was saying but I think any reasonable person would have understood that when someone says "Why can't I get electricity from a coil" they mean current and voltage. Especially since the topic of this video pertains to permanent magnets and the generation of energy. Obviously this escapes someone of your vast intellect.

[ScientistKeith]

"Obviously this escapes someone of your vast intellect. "

Why are you electing to be rude? I've been polite here. If I've made an error, I'm happy to admit it.

My intent in these posts is to discuss the topic more fully, rather than just restate what was already covered.

To the best of my knowledge, everything I said was accurate.If I made an error, kindly let me know. But there's no call to get rude over a discussion about magnets.

[BlackDogSociety]

ScientistKeith, sorry I was just trying to add a little humor to this subject. Lighten up dude, I agree with your posts...

Take Care...

[Desertphile]

"aluminum, wood, or any other non-magnetic item over it repeatedly"

All matter is magnetic: there are three different kinds of magnetism. The kind that is used to induce an electric current is within feromagnetic material.

[maintoc]

Hi, Desertphile. It sounds like you repeatedly said "amateur" instead of "armature". ~ Did you ever buy a horseshoe-shaped magnet as a kid? They usually came with a "keeper", a piece of steel that was placed across the two poles to keep the magnet strong because the steel has more magnetic permeability than air does. So, even without tapping or applying external heat, I think a permanent magnet can eventually get weak (used up) just by sitting there. It may take a long time, though.

[kmarinas86]

The energy density in the electrical field varies proportionally to the weighted-average (by volume) of the square of the electric field. During a collapse of a system consiting electric dipole moments, the energy in the electric field falls, equal to a drop in electrical potential energy. Before this potential energy becomes kinetic, it will travel according to the lines of force (magnetism). The coupling between magnetic domains via lines of force will determine the sway of particles.

[kmarinas86]

Increasing the density of like charges in conductor is done by increasing voltage. If voltage is high enough relative to the specific kinetic energy of the like charges, they will have a tendency to attach more closely to the postively ions forming the conductor material (e.g. copper). At high votage and low current densities, electrical potential energy of like charges promotes a consumption of electrical potential energy of opposite charges, momentarily adding kinetic energy to the system.

[kmarinas86]

The magnetic field is just a map showing how voltage can be transferred between particles. Voltage is potential energy per charge. Running a generator gives charges in circuit an electrical potential energy derived from the kinetic energy, which is absorbed. A motor converts electrical potential energy into kinetic energy. Electrical potential energy is lost by *seperation* of like charges or *merging* of opposite charges. Since batteries work via the former, the only other way is the latter.

[TribelessWarrior]

Asimov was,like, you know.... a god come to earth. I wish I had his brain.

[Paxmax]

good show DP!

[leporidus]

I recommend for anyone interested in EM to download the 36-part lecture from MIT Prof Walter Lewin (Spring 2002). It's card-core, systematic and rigorous, but also hilarious when he conducts experiments and demos (often with himself or a student as a guinea pig).

It's available via iTunes U. I'm at lecture 19: "How do Magicians levitate women? (with demo); Electric Shock Treatment; Electrocardiogram (with demo); Superconductivity (with demo); Levitating Bullet Trains; Aurora Borealis".

[TribelessWarrior]

That lecture series is also available in youtube under MIT's channel, lecture series 8.02

He's like Richard Feynman.

[AtheistAtLARGE]

torch it, the magnets die

[jdf088]

when a magnet is passed near a coil of wire the magnetic field causes electrons to flow through the wire and thus creating electrical current. mechanical energy is converted to electrical energy. it's really sad that some people think this is somehow free energy. i learned this shit in grade school.

[Bzdi138]

man, I subscribed just for commentary on scientology but I love this channel even though it has nothing I would typically be interested in.

As far as free energy goes; I just though that meant, govt. would get together - work to achieve massive amounts of energy from various ways and then give it to us for free because we are so deserving - alas, I was wrong :(

[SSanf]

I so much loved Isaac Asimov! When I was young, I wanted to have his baby! Unfortunately, I had no opportunity to achieve this goal. Well, perhaps, all things considered, that was a good thing.

[TribelessWarrior]

Asimov was GOD! Imagine what the world would be like if there were more of him to go around.

[wwickeddogg]

I get free energy. When I stand in the sun, I get warmer.

Is there a comparison between people who are sloppy in their physics and people who are sloppy in their language?

[frackcha]

@wwickeddogg lol... thats not free energy... its called nuclear fusion, the sun is turning hydrogen into helium.... free energy..... lol

[wwickeddogg]

@frackcha Wait a second... are we all using the same definition of free?? When I use the word free I am talking about a quality of all matter, like for example: Snickers bars are free because you can put them in your pocket when the cashier is not looking; or money is free because bank tellers give it to you if you write them a note saying you have a gun; or electricity is free if you connect to the grid yourself.

Basically all things are free as long as you refuse to pay any money for them.

[frackcha]

@wwickeddogg lol...

[mytubedude532]

You never answered my question on how you think coral castle was built. Did he use magnets?

[xtom1973]

coral castle is only one of a few strange but real mysteries

steven marks generator was also real:

watch?v=CHvuty37bTE

i guess there is "free energy" someway, but not out of magnets.

[satansmissionary6669]

Great, as always! I want to steal (most of) your videos and make them into the Junior High level curriculum for a Satanic Hindu church school. I can't believe people still credit this shit---oh, wait; Christianity, Creationism, Scientology. Disregard.

[mobiltec]

All very accurate. Lines of force.... Forcing the lines... I like it... That's how you make a magnet in the first place. Forcing all those poles to line up.

[mobiltec]

"before electronics came along."

Dang I feel old now... :(

[157626]

Great video, as usual. I hope your quote from Asimov will get more people to read him. He made science understandable. His book, "Understanding Physics" should be read by all the free energy "enthusiasts". Maybe they will finally get it.

[mandalastar]

Nevermind... You answered my question in RE:'Is this OverUnity'

[Desertphile]

"Nevermind... You answered my question in RE:'Is this OverUnity'"

ROTFL! Maybe that's where all my missing socks go, too.

[mandalastar]

I was wondering what your theory is as to where the matter goes that gets sucked into a black hole? And why do they stop feeding at times?

Maybe nobody knows the answer to these q's, but I thought if anyone does, than you probably do.

[stuffisgd]

Too long an answer to post. look up: Hawking radiation.

[TheStephenation]

Isaac Asimov was great. I haven't read the book you were holding there. I'll have to check it out.

[tjgame2]

Yes a permanet magnet will get weaker with time like 20 years of repeated use. I read a thing saying that a neo rare earth magnet will get a little stronger in the first couple years of use then level out and then start to drop off.

[maintoc]

Any idea of what makes the neodymium magnet first get a little stronger?

[tjgame2]

I am buy no means an expert but my from internet searching I think the stuff in the magnet has is not all in line together , and the more its used them few more (things) in the magnet get better in line. I dont know the tech names but I think I got the idea.

[maintoc]

Hmm, ok. I understand what you are saying. I still don't understand the "why" of it, though. Anyway, thanks for your reply.

[ScientistKeith]

It works like this:

All materials are magnetic. But the majority of them have the negative and positive fields canceling each other out. In a very few materials it is possible to align the particles in such a way to have a net magnetic field, but in most things doing so is impossible.

Just because a material can be so aligned, doesn't mean that it has been. One way to align them is to expose the material to another magnet in motion, ...[to be continued]

[ScientistKeith]

[continuation]

... which will align a few of its particles, creating a permanent magnet. If later, another such exposure to another magnet occurs, a few particles will realign. Depending on the orientation of the outside magnetic field, this will either align more particles in the same direction, creating a strong magnet; or, it will align some of its particles in the wrong direction, cancelling out the previous field, and producing an overall weaker permanent magnet.

[maintoc]

Thank you for your explanation/information.

[kmarinas86]

"Any idea of what makes the neodymium magnet first get a little stronger?"

By putting some ceramics near some neos, you can get them to be stronger or weaker, depending on the alignment. I have observed this personally with the many magnets I have been working with.

The same principle probably holds true for other types of magnets, but neos are quite strong to begin with, so it is hard to know this way.

[maintoc]

Ok, thanks, and thanks for your comment. I wonder if putting *any* kind of magnet (if they are oriented with their poles in the same direction as the neodymium one/s) near the neodymium ones would have this effect.

[Desertphile]

"Yes a permanet magnet will get weaker with time like 20 years of repeated use."

Yes, it will get weaker due to ambient heat.

[LordShadrach]

NEAT!!!

[jackferwerda]

great video. Isaac Asimov is just great and probably one of the most prolific writers ever. most likely a genius. I think he made what science fiction is today. star wars, star trek ect.. all borrowed from his books I think.

[157626]

"Isaac Asimov is just great and probably one of the most prolific writers ever. most likely a genius."

I believe the most prolific writer of the 20th century. He has something over 500 published works in nearly every subject. He was a genius's genius. Probably had an IQ off the charts. He made science understandable, and his sci-fi is some of the best in my opinion. His short essays, like the one DP quoted, are scientific gems. I hope a new generation will re-discover his genius.

[satansmissionary6669]

Mega-dittoes!!!!!

[ChrisJMoor]

You can use an electromagnet as a source of energy - sort of. When you energise it with a current electrical energy becomes magnetic potential energy. If you then cease to maintain the current the field weakens and this is equivalent to a changing magnetic field - the current continues to flow even after you turn off the source and if you break the circuit suddenly you can get quite a belt of voltage out of it, This is how car ignition system used to work before electronics came along.

[noimw]

Yes, high voltage but low current. convert that to watts to get the amount of energy. Only Joe Newman and his cult of followers thinks there is energy in voltage alone.

[ChrisJMoor]

The SI units of voltage are Kg m2 s-1 A-1 and those of energy are Kg m2 s-2. Thus they are not equivalent quantities. This is mathematical proof Newman is wrong.

Yes, the energy contained in a typical elecromagnet's magnetic field is tiny but it is still energy. As for a permanent magnet, the only way you can make energy from it is to move the magnet across the coil, thereby achieving the same effect as the collapsing magnetic field of an electromagnet when it is switched off.

[TribelessWarrior]

i wish deseretphile would make a newman video.

[kmarinas86]

Is there energy (sans power) in voltage alone? Let's check the facts:

Voltage is electrical potential energy per charge. Total electrical potential energy is voltage time charge. Of course, voltage without charge makes no sense, since voltage arises from the potential energy of charge.

A coil storing 10 coluombs at 1000 volts will have more E.P.E. than a coil storing 1 coluomb at 1000 volts. Energy needs voltage, which needs charge. To get power, charges must be at diseqilibrium.

[Desertphile]

"A coil storing 10 coluombs at 1000 volts will have more E.P.E. than a coil storing 1 coluomb at 1000 volts."

I tried to do coulomb mathematics and it was beyond me. I like watts, Joules, and just ignoring the subject entirely. :-)
