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 left. The self inductance of the loop is negligible.

a. True
b. False

Answer 1

False

Step-by-step explanation:

This is because when the loop is leaving or going out, it will experience magnetic force to the right direction.

When the loop is leaving the field, the magnetic flux present at the loop will reduce. Therefore, the induced magnetic field will have to increase the magnetic flux which means the induced magnetic flux will be in the same direction as the field.
