The coil and magnet are moved in the same direction with same speed (V). The induced e.m.f. is

Options

  1. Azero.
  2. Bproportional to V .
  3. Cproportional to V ⁻¹ .
  4. Dfinite but does not depend on V.

Correct answer

A. zero.

Step-by-step solution

e=-N d d t As the coil and magnet are moving in same direction in same speed, array ll & = B ~A = constant & ~d dt =0 array Thus, the emf induced is zero because the relative speed of magnet with respect to coil is zero.
