1.	Two identical loops , one of copper and the other of aluminium , are rotated with the same angular speed in the magnetic field . Compare (i) the induced emf and (ii) the current produced in the two coils . Justify your answer .
Answer» Since induced emf of a coil rotating in magnetic field B with angular velocity w is given by `E_(0) = N` B A `omega` and induced current `I_(0) = (E_(0))/(R)` (i) The ratio of induced emf = ` 1: 1` (ii) The ratio of induced current = `1 :1` Since , the induced emf does not depend upon the nature of coil .
