Is it possible to place 2 opposite magnets on a wheel to make the wheel turn on it’s own?

Question

Then hook up something to convert the energy from the turning wheel to make electricity (like a windmill without the wind)?

Would it really be a perpetual motion machine if eventually the magnets wear down and need to be replaced? I would assume it could turn for a while, but not forever. So yes I’m asking if it can power its self, but not asking for a perpetual motion machine.

If the wheel was pushed by the magnets, like if the wheel was a metal that reacted to the magnets, couldn’t the magnets naturally push it, thus turning the wheel… and then just use it like any other windmill?

I’m not asking for the magnets to produce it, I’m asking can I make the magnets turn a wheel, like how those trains on magnet rails move… it if turns the wheel, then you could just get the other parts from a windmill to make it produce energy, yes no? So can you make a metal wheel that turns from the push of a magnetic field from magnets?

Answer 1

There is no smoking gun saying no it is not possible. However, every credible piece of evidence since Galileo says it is not going to happen.

Answer 2

I thought of the exact same thing when I was about 12 ( a few short years ago) whaen I was thinking about how an electric motor worked. In fact there are many bogus offers you can find for 'free energy' with that exact idea. the thing is, the magnets will repel, but will not cause spinning motion. The only reason that an electic motor works is because the poles on either the inner or the outer magnets reverse every half rotation, causing a constant pull. If there were some non-electric magnets which could do this, it would work.

Answer 3

What you have just described is a perpetual motion machine, and it is impossible. To put it in simple terms 'you can't get something from nothing.' You can put two magnets on a wheel and turn the wheel to generate electricity, but you must do work to turn the wheel; it won't turn on its own.

In fact, a perpetual motion machine is one of the only things that the US patent office requires a working model to aquire a patent for, because they have recieved so many bogus claims of perpetual motion machines without proof. Unfortunately, while it would be great if someone could build one, the fundamental physical law of conservation of energy as well as the laws of thermodynamics state that this can never be done.

Answer 4

No. Were that the case, you would have invented perpetual motion.
Like turning lead into gold, generating endless energy is a dream a thousand years and more old.
It's a pity, but the best we can do is turn the wind energy into electricity by turning a coil of wire through a magnetic field (that is, attaching the windmill to a generator).
Cheers.

Answer 5

No. You can not have a perpetual machine :) Some of the energy is lost to angular momentum, some to friction. In all cases, energy in must = energy out. You are not adding any energy in a magnet-type system, so eventually all energy will be lost.
You can make something move forever, like shooting something into space really hard, but you can never make use of that motion.

Answer 6

Swell idea.
They call that little gimmick a motor

edit - oh but you want to get it to power itself?
nope
that would be a perpetual motion machine, which violates the laws of thermodynamics....

another edit - looks like you were really tryin to crank this one down to a nub, and I dig your persistence,
but still nope
even if you had your very own superlab stocked with trained techs, and high-end manufacturing facilities making exactly all the components you wanted, when you put them all together, you would still have a machine that lost energy in the form of friction in your bearings, heat generated by pushing current through wires against resistance, or hell, even just plain old wind resistance....
Run it in space?
still nope
Use superconductors?
getting closer
but still nope
the best you could ever produce, even ideally
would be something that ALMOST did it
Energy losses of one kind or another are impossible to reconcile, now matter how imaginitive you get....
The only example I've ever heard of where something produced more energy than it absorbed -
Fat Man
Little Boy
or
those guys that wanted to make something HOT, so they ran massive amounts of current through some steel filaments (vaporizing them into plasma), yielding temps hotter than the core of our intrepid sun....
Good luck to you!
Keep thinking like you do, and maybe change the world for us someday! :)

Answer 7

This has been tried many times, as people have searched for ways to create "free energy".

Unfortunately, it doesn't work - nor has any free-energy system since the "Perpetual Motion" machine hoaxes of a hundred-or-so years ago.

One of the primary laws of physics is that energy can neither be created, nor destroyed. However, it can be transferred from one object to another - in the form of heat, motion, distortion, or something else. So, if you see a person pushing a "free energy" device or design, and if it appears to actually work, just remember - whatever's output from that thing, is getting *input* from something else. There's a trick to it. ;)

Answer 8

No. Magnets alone cannot create a perpetual machine.

Answer 9

You are thinking about magnets on a wheel, every magnet has two poles.
Monopole magnet might help you design such wheels. But there is no monopole magnet.

Answer 10

"magnetic trains" use magnets just to lift themselves in the air. forward motion comes from something else.

Answer 11

if any of two out of three viz Magnetic field,motion and elc. current ,are available, the remaing third one is produced. magnets only can not produce motion
