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. (True or false)

Upon entering the field, a counterclockwise current flows in the loop.

While the loop is entirely in the field, the emf in the loop is zero.

When entering the field the coil experiences a magnetic force to the right

When leaving the field the coil experiences a magnetic force to the left.

Explanation / Answer

1) true

2) true

3) false

4) true

by using right hand thunmb rule

by using len's law also we need to find the direction of current
