Asseration:The induced e.m.f. and curent will be same in two identical loops of copper and aluminium, when rotated with same speed in the same magnetic field.
Reason:Induced e.m.f. is proportional to rate of change of magnetic field while induced current depends on resistance of wire.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
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.
