Physics-Motional EMF
NEET Physics Motional EMF MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about motional EMF is correct?
A
Motional EMF is induced only when there is a change in magnetic flux through a closed loop.
B
A steady magnetic field can induce EMF if a conductor moves through it at high speed.
C
The induced EMF remains constant regardless of the speed of the conductor in the magnetic field.
D
The direction of the induced EMF depends solely on the motion of the conductor relative to the magnetic field.
Correct Answer
Option A
Detailed Explanation
Motional EMF is induced only when there is a change in magnetic flux through a loop, as noted in the context that current can only be induced by changing magnetic flux and not by a steady magnetic field.
