A square loop of side 15 ~cm being moved towards right at a constant speed of 2 cm / s as shown in figure. The front edge enters the 50 ~cm wide magnetic field at t= 0 . The value of induced emf in the loop at t=10 ~s will be :

Options

  1. A0.3 mV
  2. Bzero
  3. C4.5 mV
  4. D3 mV

Correct answer

B. zero

Step-by-step solution

At t =10 sec complete loop is in magnetic field therefore no change in flux e = d dt =0 e =0 for complete loop
