Motional EMF

A straight conductor of length 0.6 M is moved with a speed of 10 ms−1^{-1} perpendicular to magnetic field of induction 1.2 weber m −2^{-2}. The induced e.m.f. across the conductor is

Show answer and solution

Answer: (b)

  1. ε=Blv\varepsilon = Blv
  2. ε=1.2×0.6×10=7.2\varepsilon = 1.2 \times 0.6 \times 10 = 7.2 V
  3. So the answer is (b) 7.2 V.
