Type: MCQ-diagram based-Medium-Class 12
In the diagram shown above, what is the effect of increasing the speed of rotation of the wheel on the induced emf between the axle and the rim?

A
The induced emf increases.
B
The induced emf decreases.
C
The induced emf remains constant.
D
The induced emf becomes zero.
Correct Answer
Option A
Detailed Explanation
Increasing the speed of rotation increases the angular velocity, which in turn increases the induced emf according to the formula .
