The Faraday's induction law states that the temporal variation of the magnetic flux induces an electromotive force, according to the following expression:
I know how this law works on a whorl, coil, but not for a volumic body. How I should write the Faraday's induction law for a solid cylinder? I'm studying induction motors, and so, I need to know how is current inducted on the rotor (cylinder). Should I assume that the current only appears on the surface? Should I assume some "whorl density" like we do for the coil?
I can't find any information on internet about this topic. Do you know some interesting books or sites?
