Magnetic Motor

Magnetic Motor
Can you please explain how a magnetic DC Motor ( with a commutator ) and a Magnetic AC Generator works ?

( Just the basics? )

Why does the armature spin continuously in both?

I really do not understand , why does the current alternate in an AC generator anyways?

how do the slip rings work
?

Browse this outline. It's basic, and clear.

The rotor does indeed spin continuously in both. This is necessary because the interactions between rotor and stator are because of the difference between their magnetic field orientations.

Slip rings let stationary contacts on the motor frame to transfer power to/from the rotor even while the rotor spins.
