1. A circular coil, with radius of 10 cm, and 25 turns, rotates in a constant magnetic field of strength 2.4 T, with the axis of rotation perpendicular to the direction of the magneticfield.
A. If the coil rotates at a frequency of 50 Hz, what is the induced peak voltage?
B. Sketch the time-dependence of the induced voltage.
C. If the magnetic field that the coil is in points down the page, which direction does the coil rotate? Answer for both cases: (1) q traveling from left to right and (2) q traveling from right to left in the coil. (Draw a diagram to help you.)
