NEET Physics Motional EMF MCQ Question
Which of the following statements about motional EMF is correct?
Motional EMF can be generated by moving a conductor through a magnetic field, leading to a separation of charges within the conductor.
The magnitude of the motional EMF is independent of the speed of the conductor moving through the magnetic field.
Motional EMF only occurs in closed circuits and cannot be generated in open circuits.
The induced EMF in a moving conductor is always in the opposite direction to the motion of the conductor.
Correct Answer
Detailed Explanation
Motional EMF arises when a conductor moves through a magnetic field, causing charge separation due to the Lorentz force as described in the context. Options B, C, and D reflect misconceptions about the relationship between speed and induced EMF, the conditions for EMF generation, and the direction of induced EMF.
