| 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]: The induced emf in a conducting loop of wire will be non zero when it rotates in a uniform magnetic field. |
| Reason (R): The emf is induced due to change in magnetic flux. |
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: A
Solution :
(a) As the coil rotates, the magnetic flux linked with the coil (being \[\overrightarrow{B}\cdot \overrightarrow{A}\]) will change and emf will be induced in the loop.
