| Directions: In the following questions, a statement of Assertion [A] is followed by a statement of Reason (R). Mark the correct choice as: |
| Assertion [A]: Changing magnetic flux can produced induced emf. |
| Reason (R): Faraday established induced emf experimentally. |
A) Both Assertion [A] and Reason (R) are true and Reason (R) is the correct explanation of Assertion [A]
B) Both Assertion [A] and Reason (R) are true but Reason (R) is not the correct explanation of Assertion [A]
C) Assertion [A] is true but Reason (R) is false
D) Assertion [A] is false and Reason (R) is also false
Correct Answer: B
Solution :
(b) emf induces, when there is change in magnetic flux. The magnitude of induced emf depends upon the rate at which the magnetic flux changes. When magnetic flux is steady or constant no emf is induced. Faraday did experiment in which, there is relative motion between the coil and magnet, the flux linked with the coil changes and emf induces.
