A conductor of length 100 cm moves right angles to a magnetic field of flux density of 2 wb/sq.m. with the velocity of 25 m/second. The induced emf in the conductor will be
- A. 25 volts
- B. 50 volts
- C. 75 volts
- D. 100 volts
Answer: B. 50 volts
Explanation: Induced EMF e = B·l·v·sin θ = 2 Wb/m² × 1.0 m × 25 m/s × sin 90° = 50 V.
