Question

the rectangular loop shown in the figure moves at a constant velocity normal to a stationary and uniform magnetic field. determine theelectromagnetic force induce across a small gap created in the loop. the loop sides are a and b.

Answer 1

The force should be zero because Faraday's Law says \[EMF = \frac{ d\Phi_B }{ dt }\].
The change in magnetic flux (Phi sub B) is zero because the area of the loop isn't changing and the B field is uniform.
