Find the average e.m.f and the current




A coil of resistance 100 ? is placed in a magnetic field of 1m Wb. The coil has 100 turns and a galvanometer of 400 ? resistance is connected in series with it. Find the average e.m.f and the current if the coil is moved from given field to a field of 0.2m Wb in 0.1 second.
