Grade upto college level Magnetism
Q. A circular coil A of 100 turns and radius 2 cm, is placed co-centrically inside another circular coil of B of 1000 turns of radius 20 cm, both being in the same plane. When the current in the coil B decreases from 5A to 3A in 0.04s, the induced enf in the coil A is : a) 1.97 mV b) 2.53mV c) 1.53mV d)1.06mV
Plz expail it elaborately.
