NEET Physics Motional EMF MCQ Question
Type: MCQ-numerical-Hard-Class 12
A straight conductor of length 1.5 m moves at a speed of 2 m/s perpendicular to a magnetic field of strength 0.5 T. What is the magnitude of the motional emf induced in the conductor?
A
1.5 V
B
0.75 V
C
1.0 V
D
3.0 V
Correct Answer
Option A
Detailed Explanation
The motional emf is given by the formula Blv, where B = 0.5 T, l = 1.5 m, and v = 2 m/s. Plugging in these values gives emf = 0.5 * 1.5 * 2 = 1.5 V.
