## Main Question or Discussion Point

Hi,

In classical induction machine analysis, the induced voltage (or curl of the electric field) is equal to the time rate of change of the magnetic field (B) plus the 'speed voltage'. This is understood very easily from electrical circuit models of the machine.

However, going purely from Maxwell's equations (1. div(E) = rho/epsilon; 2. div(B) = 0; 3. curl(E) = -dB/dt; 4. Curl(B) = mu(J + epsilon*dE/dt) ) how can one arrive at the same observation as above?

Thanks
