| Assertion: The induced e.m.f. will be same in two identical loops of copper and aluminum, 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 reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) if assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
Since both the loops are identical (same area and number of turns) and moving with a same speed in same magnetic field. Therefore, same e.m.f. is induced in both the coils. But the induced current will be more in the copper loops as its resistance will be lesser as compared to that of the aluminium loops.
