A 75 turn, 10.0 cm diameter coil rotates at an angular velocity of 8.00 rad/s in a 1.20 T field, starting with the normal of the plane of the coil perpendicular to the field. Assume that the positive max emf is reached first. (a) What (in V) is the peak emf? (b) At what time (in s) is the peak emf first reached? (c) At what time (in s) is the emf first at its most negative? (d) What is the period (in s) of the AC voltage output?
