| Directions : (1-37) For Assertion and Reason Type Questions |
| In this type of question, a statement of assertion [A] is followed by a statement of reason [R]. Mark the correct choice as : |
| Assertion: Changing magnetic flux can produce induced e.m.f. |
| Reason: Faraday established induced e.m.f. experimentally. |
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 :
e.m.f. induces, when there is change in magnetic flux. The magnitude of induced e.m.f. depends upon the rate at which the magnetic flux changes. When magnetic flux is steady or constant no e.m.f. is induced. Faraday did experiment in which, there is relative motion between the coil and magnet, the flux linked with the coil changes and e.m.f. induces.
