Induction law

In this case, the enclosed B field changes in the coils when the magnet is rotated.

The alternating voltages produced are each phase-shifted by 120°.

A voltage is only a difference of the number of electrons. The magnetic field of one pole presses when the coil passes away the electrons. The other pole pulls her back. Large magnetic field, large coil = large voltage. Faster turning equal to higher frequency. This is very simplified, but I think this is the trivial experience.

Here, three-phase current is generated because the coils are offset by 120°.
