Question

A straight conductor 25cm moves at 30m/s in 0.4T field. If resistance is 0.8Ω, calculate current.
Options
A 0.72A
B 3.75A
Correct Answer
C 1.25A
D 0.48A
Correct Answer

Option B is the correct answer.

Detailed Explanation

EMF = BLv = 0.4 × 0.25 × 30 = 3V. I = EMF/R = 3/0.8 = 3.75A.

Hint

Motional EMF = BLv.
