wow you should start that up
try it, or have someone try it for you
I've always wanted to see why they couldn't have a motor that runs on water, then I heard they were already doing that

It can and it has. But here is the better question for you. How to power it. A compass is powered by magnets, both the earths natural as well as counters to provide for true north.
And the MAIN problem with your idea is... the needle moves in ONE direction. So we would have a HUGE car sale at the north pole as all the cars would end up there. .... OR how do you keep the car spinning enough to keep the compass power going?
The engines that have been built are very experimental and do NOT solve these problems, and until you can overcome things like gravity and natural pull, it will never work.

Yes, a heavy compass needle will move - but only until it points north, then it stops moving. If you can change the position of the poles, you can keep the needle moving. Make it smaller, use the idea of electromagnetism, and you have the electric motor.

An engine, or motor needs to spin in one direction or another to keep the vehicle moving. The only thing I can think of is for the magnet "needle" (attached to the crankshaft) being able to somehow use a slingshot effect to point north, overshoot it, and rotate again and again. Is that sorta what you meant?

A compass needle is simply a magnet. Lots of motors are based on that principle.

It requires very little torque to move a magnetized lever. Try moving a motor with significant mass. Throw even a small magnet on a wooden table and see if it moves. The earth;s field is very weak. Nails don't fly to the north.

How much is considerable mass?? I have never seen a 1.4 ton compass needle.

While the needle moves north, you could amass energy. To move it back you would need the same amount of energy, even more.
Electrical motors work on the basis of magnetism already.

Do u know electric engine r designed/ manufactured on the principle of magnet, i mean electric motor.

It probably can be but what;s the point?
