The magnet is moved towards the coil with speed ' V '. The induced e.m.f. in the coil is ' e '. The magnet and the coil move away from one another each moving with speed ' V '. The induced e.m.f. in the coil is

Options

  1. Ae
  2. B2e
  3. Ce 2
  4. D4e

Correct answer

B. 2e

Step-by-step solution

The equation for the induced emf is: e = B l ~V Relative velocity between the coil and the magnet is: v _ r =2 v The new induced emf in the coil is: e _ new = B l 2 ~V =2 e
