Question

Do you think we could make a car run on MAGNETS???

Answer 1

Not really.

You could have an enormous bar magnet in the car with its North pole at the front and South at the back, one at the beginning of the road with its South pole facing towards the car and one at the end of the road also with its South pole facing towards the car, so that the car would be repelled from one and attracted towards the other.

However, due to the repulsive force, it would take an enormous effort to get the car anywhere near first magnet  (it would be like compressing a very big spring -- the work done against the repulsive force is stored up as PE); and once it had stuck to the second magnet, due to the attractive force it would take an equally enormous effort to move it away.

No matter how you try to balance a bunch of permanent magnets, they will always come to rest in a stable position where either they are all stuck together by attraction, or the repulsive forces cancel out.

The only way you can avoid stable states is to have one of the magnets changing its polarity all the time.  Then, as it is getting close to the magnet attracting it, it has to swap its poles over somehow so it gets repelled instead -- and thanks to inertia, it will continue to move in the same direction it was already going.  That requires one of the magnets to be an electromagnet; but Michael Faraday already had that idea, about 150 years ago.

Answer 2

Probably, but you'll probably have to get it moving initially or never stop it.

It might have a problem with hills.

Answer 3

Not really, magnets are not source of , or a storage medium for energy, however electric motors do make use a magnets, but the electricity has to be supplied by something else.

Answer 4

YES, without a doubt.

I think our government has technology that they do not want us to have yet.  There has been no significant technology bursts in ten years, and I'm waiting for one.

Answer 5

no.

The "magnetic motor" is a perpetual motion motor attempt that has been kicking around for many years. No one has been able to get it to work, and for a very good reason:

It violates the basic laws of physics, like conservation of energy.

It will never work.
