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

average current = average induced emf / resistance
= - (0.3 - 0.1)*10^-3 * 500 /(150+450) Amp
= - 1/6000 Amp = - 0.167 mA
= - (0.3 - 0.1)*10^-3 * 500 /(150+450) Amp
= - 1/6000 Amp = - 0.167 mA
