We all know that magnets of the same poles repel each other. Can we use that behavior of a magnet to run the motor of a small fan?

Well actually that's how a motor works but instead of having two fixed magnets, we have one fixed magnet and an electromagnet that varies with the incoming voltage for an AC fan or an electromagnet that switches poles for DC current using brushes and a split armature.

No...magnets won't be able to be used to create ability by employing themselves. they may be used as an opposing magnetic field in a motor or a noisy speaker, for occasion, even with the undeniable fact that it is the electrical powered cutting-edge in the process the cord windings interior the device that produces the action. Magnets own means ability that's gifted into the magnetic cloth by employing an outdoors source of ability - and if the like poles are close adequate, this means ability will certainly grow to be kinetic ability. If magnets by myself could create ability, a perpetual action device could quickly be drawing near.

No. the trouble with that is that when the magnet in the shaft is approaching the stationary magnet that same repulsion will brake the shaft equally proportional to the "push" and the equivalent movement will be 0. If you succeed call me.

It can be done with electromagnets. Years ago they used to manufacture Repulsion-Induction motors that worked on that principle. They had brushes and windings much like a DC motor and therefore complex. With the invention of simpler Induction motors, they have disappeared.

NO, perpetual motion machines just don't work.
