## Main Question or Discussion Point

I have been trying to calculate the voltage and current induced in a stator by a rotor of permanent magnets. The formula Length x Velocity x the B-field , i understand most of. My question is about the Length part of the formula, in a stator the wire passes through the iron core, so is the length that the formula refers to the small section that passes though the iron core or is it the total length of the wire in each phase of the 3 phases in the stator? As an example: if the velocity was 13.5 m/s and the B-field was 6500 gauss and assuming that the length is total wire length of the phase was 76m, i get 13.5m x .65 T x 76m = 666 volts but that doesnt look rigth to me. any help would be greatly appreciated
