WebAs explained in Induced Current in a Wire, motional emf in a straight wire moving at velocity v through a magnetic field B is E = B ℓ v, where the velocity is perpendicular to the magnetic field. In the generator, the velocity makes an angle θ with B (see Figure 20.27 ), so the velocity component perpendicular to B is v sin θ. WebQuestion 8. Mutual inductance is the term given to the phenomenon where a change in current through one inductor causes a voltage to be induced in another. When two inductors (L 1 and L 2) are magnetically “coupled,” the mutual inductance (M) relates their voltages and currents as such: e 1 = M. di 2. dt. Voltage induced in coil 1 by change ...
