Problem 3.334

There are two stationary loops with mutual inductance $L_{12} .$ The current in one of the loops starts to be varied as $I_{1}=\alpha t$ where $\alpha$ is a constant, $t$ is time. Find the time dependence $\bar{I}_ {2}(t)$ of the current in the other loop whose inductance is $L_{2}$ and resistance $R$.
