Question

A square loop of wire with a small resistance is moved with constant speed from a field free region into a region of uniform B field (B is constant in time) and then back into a field free region to the right. The self inductance of the loop is negligible. When entering the field the coil experiences a magnetic force to the right. Upon leaving the field, a clockwise current flows in the loop. When leaving the field the coil experiences a magnetic force to the right. Upon entering the field, a clockwise current flows in the loop.

Explanation / Answer

a)true

here,

coil is entering into the field ,

the direction of the force is towrds right

b) true,

the indued current flows in a clockwise direction

c) false,
the direction of the magnetic force is towards left

d) false,

the indued current flows in a anticlockwise direction
