An AC generator consists of 8 turns of wire in a loop or coil, the cross-sectional area of the loop is A=0.09 m2, with a total resistance of 12Ω. The loop is rotating in a magnetic field B=0.5T at a constant rate of 60Hz.
A) Discover the maximum EMF and current induced in the coil;
B) Inscribe the equations for the time variation of the induced EMF and current.
