question

A square coil of 50 cm^2 area consisting of 20 loops is rotated about a transverse axis at the rate of 2 turns per second in a uniform magnetic field of flux density 500 gauss. The coil has a resistance of 20 ohms, (a) What is the average electromotive force induced in the coil during one quarter cycle of a revolution? (b) What is the average current in a complete cycle? (c) How much charge is passed through the coil in this interval?
