Question 44
Electromagnetic InductionA conductor of length 1m moves with a velocity of 50ms−1 at an angle of 30° to the direction of a uniform magnetic field of flux density 1.5Wbm−2. What is the e.m.f. induced in the conductor?
- A.37.5V
- B.50.5V
- C.75.0V
- D.80.5V.
Show the answer and explanation
Answer: A (37.5V)
Explanation
E = BLv sin θ = 1.5 × 1 × 50 × sin 30° = 37.5 V.
