Statement I: The induced emf and current will be same in two identical loops of copper and aluminium, when rotated with same speed in the same magnetic field.
Statement II: Induced emf is proportional to rate of change of magnetic field while induced current depends on resistance of wire.
In the light of the above statements, choose the most appropriate answer from the options given below

Verified by ExpertsC
Statement I is incorrect but Statement II is correct.
Since, both the loops are identical (same area and number of turns) and moving with a same speed in same magnetic field. Therefore, same emf is induced in both the coils but the induced current will be more in the copper loop as its resistance will be lesser as compared to that of the aluminium loop.
