The magnetic field in a region is given by B=B0xak^. A square loop of side d is placed with its edges along the x and y axes. The loop is moved with a constant velocity v=v0i^. The emf induced in the loop is :

  1. B0v02 d2a
  2. B0v0d2a
  3. B0v0d2a
  4. B0v0d22a

Solution

E1=B0x+dav0d

E2=B0xav0 d

Enet=E1-E2

Enet=B0v0d2a
