Introduction

A solenoidal coil with $22$ turns of wire is wound tightly around another coil with $330$ turns. The inner solenoid is $25\mathrm{.}0$ cmcm long and has a diameter of $2\mathrm{.}10$ cmcm$.$ At a certain time, the current in the inner solenoid is $0\mathrm{.}100$ AA and is increasing at a rate of $1800$ A$/$sA$/$s$.$
