Question

A coil of resistance 150 Ω is placed in a magnetic field of 0.1mWb. The coil has 500turns and a
galvanometer of 450 Ω is connected in series with it. The coil is moved in 0.1s from the given field
to another field of 0.3mWb. Find the average induced emf and the average current through the coil.

Answer 1

so the answer is 120 ohms.
