NEET Physics Motional EMF MCQ Question
Which of the following statements about motional EMF is correct?
Motional EMF is produced by moving a conductor in a magnetic field.
The induced EMF depends only on the length of the conductor.
Motional EMF can be generated without any motion of the conductor.
The direction of induced EMF is always opposite to the motion of the conductor.
Correct Answer
Detailed Explanation
Motional EMF is indeed produced by moving a conductor in a magnetic field, as described in the context about the expression Blv for induced EMF. The other statements reflect misconceptions about the conditions necessary for generating EMF.
