An AC generator consists of eight turns of wire, each having area A =9.0x 10-2 m2, with a total resistance of 12.0 V. The coil rotates in a magnetic field of 0.500 T at a constant frequency of 60.0 Hz, with axis of rotation perpendicular to the direction of the magnetic field. (a) Find the maximum induced emf. [3] (b) What is the maximum induced current? [1] (c) Determine the induced emf and current as functions of time. [2] (d) Wiat maximum torque must be applied to keep the coil turning? (3)​
