NEET Physics Motional EMF MCQ Question
Which of the following statements about motional EMF is correct?
Motional EMF can be induced by a conductor moving within a constant magnetic field.
The induced EMF is constant for both rectangular and circular loops moving through a magnetic field.
Current can be induced by changing the electric flux through a conductor.
The direction of induced current in a conductor is always opposite to the motion of the conductor.
Correct Answer
Detailed Explanation
Motional EMF is produced by the movement of a conductor within a magnetic field, as stated in the context. The induced EMF is not constant for all shapes of loops, and current cannot be induced by changing electric flux, but rather by changing magnetic flux.
