Physics-Motional EMF
NEET Physics Motional EMF MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Which of the following statements about motional EMF is correct?
A
Motional EMF is generated when a conductor moves through a magnetic field, leading to charge separation.
B
Motional EMF can only be produced by varying the magnetic field strength, not by moving the conductor.
C
The direction of the induced EMF is opposite to the motion of the conductor in the magnetic field.
D
Motional EMF increases as the magnetic field strength decreases.
Correct Answer
Option A
Detailed Explanation
Motional EMF is indeed generated when a conductor moves through a magnetic field, causing charge separation due to the Lorentz force, as mentioned in the context. The other options present misconceptions about the nature of motional EMF.
