NEET Physics Motional EMF MCQ Question
Type: MCQ-numerical-Medium-Class 12
A straight conductor of length 0.5 m is moving with a velocity of 20 m/s perpendicular to a uniform magnetic field of 0.1 T. What is the magnitude of the motional emf induced across the ends of the conductor?
A
0 V
B
0 V
C
0.5 V
D
0.1 V
Correct Answer
Option A
Detailed Explanation
The motional emf is calculated using the formula , where is the magnetic field, is the velocity, and is the length of the conductor. Substituting the given values, V.
