Question

A straight conductor 0.1 m long moves in a uniform magnetic field ).1T. The velocity of the conductor is 15 m/s and is directed perpendicular to the field. The e.m.f. induced between the two ends of the conductors is.

• A. 0.10 V
• B. 0.15 V
• C. 1.50 V
• D. 15.00 V

Answer 1

Answer: (B)

0.15 V

$\epsilon =BvI=0.1\times 15\times 0.1=.15V$(considering B, and v are mutually perpendicular)
