Halbach magnetic motor

[KirkMcLoren]

and this is supposed to turn why?

ever hear of symmetry?

[umrox1]

what if you put magnetic shielding on the sides of the two sets of magnets?

[viking1au]

More meaningless crap!

Hey Permanent magnets WITH ! earth magnet DOES NOT LOOSE ITS POWER FASTER OR EQUALLY FAST AS THE USED ENERGY COSTED TO BUILD THEM !

IT COULD RUN FOR 50-100 YEARS EASY !!!

Rare Earth Magnet does not loose its magnetism at all but with much energy it can be temporarily made non magnetiv , but it would have to be completely destroyed out of the world if not to gain its magnetism soon back again..

google for facts if you cant read a book ;-)

Yo he probado un motor con hallbach array y si que funciona , espero recibir dentro de poco mas imanes para demostrar este funcionamiento



[ArrEffburn]

Permanent magnet motors are possible, but you will never get more energy out of the device than it took to create the magnets in the first place. Go do a little reading on how they are made, it requires quite a bit of energy. Over time they lose their magnetism, and very rapidlyt when used in a permanent magnet motor.

[Superman83271]

@ArrEffburn I agree but I wonder if the cost of building a magnetic motor would be less than the energy you could get from it during the life of the magnets and the motor?

[gibbo1112]

@ArrEffburn true you will never get as much energey out as what was put in, but if you read the books you tell use to read you would know just how much energy it takes to magnetise a permanent magnet, and that they can last a minimum of about 100 years before any sign of losing magnetism, though magnet motors dont work...

[ArrEffburn]

Hey mysql0, You commented to me that a permanent magnet motor would not lose it's magnetism, and an example of this was a car alternator. Well, you need to disassemble a car alternator sometime soon. They don't use permanent magnets, they use an electromagnet, or what's known as a field coil. Since the rpm's of the engine cannot be regulated, the voltage regulator will instead adjust the amount of current in the field coil, thus regulating the voltage output. No perm magnets are used.

[mysql0]

@ArrEffburn The alternator in my car uses a permanent magnet, instantly disproving what you said.

In addition, my electric fan in my bedroom which runs with an electric motor (containing a permanent magnet and an electromagnet, thats how motors work) has been running well for almost 12 years and is still just as strong as it ever was, further disproving your "Magnets run out of steam when they are under a lot of use"

[mysql0]

@ArrEffburn What about the Hoover Hydroelectric Dam, built in 1968 and still running today? It generates electricity by spinning a magnet, surely this magnet would have run out by now, 42 years later if your stupid "Magnets run out of steam under lots of use" theory were true.

IDIOT!!!

[ArrEffburn]

@mysql0 The Hoover Dam and your electric fan do not use permanent magnets.

Large power plants use field coils and exciters, (electro magnets) . Your fan uses a rotating magnetic field created by a phase shift capacitor between two 90 degree facing coils. The center of the motor is just a plain old piece of iron. There's no free energy, just free half baked answers from you. A child's toy might have a DC motor with a permanent magnet, but they loose torque with age. Perm magnets aren't permanent

[mysql0]

@ArrEffburn Wrong, wrong, and triple wrong.

The Hoover Hydroelectric dam does in fact use large permanent magnets. The water rotates these magnets as it passes and these spinning magnets spin next to a large coil of copper, which generates the alternating current. The dam requires both permanent magnets and coils of copper.

Instead of denying it go research it, you can clearly see this dam has been using it's magnets for the past 43 years.

You said they run out really fast under use - WRONG!!

[ArrEffburn]

@mysql0 Sorry, but they use residual magnetism in their iron cores, not permanent magnets. It's simple engineering if you think about it. There's no need for permanent magnets because they can't compete with electro magnets for flux density. You want as much flux as possible to be effecient. Thus, the Hoover Dam doesn't use permanent magnets. And your electric fan still doesn't either. The eddy currents and heat would scramble the domains like those in your head.

[mysql0]

@ArrEffburn Actually I took apart my 10 year old electric fan last night after your comments just to double check, low and behold it contains permanent magnets.

How odd eh?

These permanent magnets under heavy use have not "run out" or "significantly weakened" at all, still just as strong, thus proving your "Even if there is a free energy magnet motor the magnets will run out very quick" - Wrong.

[ArrEffburn]

@mysql0 I visited the Hoover Dam with my family when I was 10. Even at that young age I had the presence of mind to ask the tour guide about how the "exciter" worked on top of each generator. He told me it was used to control the field winding current in the larger generator ........see, no permanent magnets.

[mysql0]

@ArrEffburn Your 10yr old story is either A) made up lie OR B) you were honest so the tour guide was totally wrong

The Hoover Dam uses large extremely powerful permanent magnets.

Since it has been running for 43 years under constant use, then your "magnets run out faster under a lot of use" theory is wrong.

[ArrEffburn]

@mysql0 go to this page and read about the design of the generators at Hoover Dam. There are no permanent magnets in the generator, just an exciter that powers the rotor, or field coil. Look near the bottom of the page.

[ArrEffburn]

@mysql0 Huh ? 43 years ?? ...If the Hoover Dam has been using it's permanent magnets for the last 43 years, then they must have replaced them in 1968, because the Dam came online in 1936. Are you admitting that the magnets (which only exist in your mind) were replaced after the first 32 years? See, even when your facts are wrong you still admit they're not permanent.

[mysql0]

@ArrEffburn Wait a minute. I said they were running for 43 years. Now you found out that they have actually been running for 75 years! This proves my point even more.

You saw this mistake as "haha i win he got a fact wrong", when in reality all you have done is strengthened my case even more! 75 years :)

Let's forget the hoover dam for a moment, my electric fan in my bedroom using permanent magnets is still as strong as ever, thus disproving your "magnets run out faster under lots of use"wrong

[ArrEffburn]

@mysql0 Here is a quote from eamagnetics

A permanent magnet will retain its magnetism unless it is affected by a strong outside magnetic or electrical force, or elevated temperatures. If they are not exposed to any of these conditions, permanent magnets will lose magnetism on their own, however this degradation is very slow, on the order of one percentage point every ten years or so.

[ArrEffburn]

Putting a permanent magnet in an electric motor would subject it to exactly what you don't want it to be exposed too. High temperature and high flux, or electrical force. It will work for a while, like in a childs toy, but not for long. When building things to last like the Hoover Dam, engineers don't use permanent magnets. Now flux off.

[ArrEffburn]

@mysql0 Search wiki for "black start". It is a procedure Electric plants use because they cannot start their generators on their own, they must be fed current to power their field coils from another source. This is because they do not use permanent magnets.

[fronkenpoop]

Nope.

[Flabbergast101]

im getting really tired of seeing these dumbass computer models. Everytime someone shows one of these and then tries to make it, it fails.

STOP POSTING THEM.

Make the computer model, make the testing model, and if it works THEN POST THEM ON YOUTUBE YOU DUMB FUCKS WASTING MY FUCKIN TIME

[TheJimmax]

@Flabbergast101 ok i agree but chill dude!

[ILoveSoImAlive]

it will just stop at ca 0:07 and thats all.

[greenhorny11]

hi this doesn't work, because you didn't realize how the array works... the magnetic field gets from one magnet into the other because there is less resistance, in the aaray a northpole has on both sides southpoles, so the fieldlines go this way, but if you put an magnet with a southpol near the halbach array, the field lines will go this way and the weel will stop, I'm sorry to tell you

[superstitionadd]

@greenhorny11 Try moving 2 Halbach arrays near each other on 'Visimag' and then see if you want to repeat your statement.

[jotacril]

Doesn't work because violates one of the thermodynamic laws.

All the devices that try to take advantage of an "hole" of gravity are designed as "unbalanced wheels".

They are studied since the 11th century and none worked till today.

[bruckator]

@jotacril

the Takahashi Engine for example violates one of the thermodynamic laws too, but it works anyhow.

[TheUnknownSkeptic]

If this really works, a prototype device would be pretty inexpensive to build. I wonder why we've never seen one...

[reason245]

This won't work, the rotating arrays wouldn't get past the fixed ones.

You should get the big ben chime of wrongness. WRONG WRONG WRONG WRONG....WRONG WRONG WRONG WRONG.......WROOOONGG.

[Aerensiniac]

@reason245 Check out the Clanzer Clearing videos. The concept works.

You get the big ben chime of failness. FAIL FAIL FAIL FAIL....FAIL FAIL FAIL FAIL.......FAAAAAIILL.
