Question 43

Electromagnetic Induction

The magnetic flux in a coil having 200 turns changes at the time rate of 0.08 Wb s−1. The induced e.m.f. in the coil is

  1. A.1.6 V
  2. B.16.0 V
  3. C.25.0 V
  4. D.250.0 V
Show the answer and explanation

Answer: B (16.0 V)

Explanation

E = N × rate of change of flux = 200 × 0.08 = 16.0 V.
