Well i had seen a toy, which i till date don't know was it battery powered or not? and also could it be used to actually create energy (I know that it is not possible but whats the problem?)
Structure of a toy: Imagine a toy man having magnets at his feet, he is fixed to an axle and can just perform a motion in forward or backward direction, and also note that at the base of the man's feet (attached to that axle) is another magnet with same pole as that of the magnet of feet.
What was happening: What was happening was that the man was continuously performing the motion and not stopping at all.
The thing is that i saw it from a distance and so i could not know that wheter or not it used battery
Questions Will it stop? Will it generate electricity forever if i put an turbine to at the axle 1. On Earth 2. In outer space 3. Under gravity + No Friction
Well i know the simple answers in of most of them in form of yes/no but Why?
