A coil of wire having finite inductance and resistance has a conducting ring placed coaxially within it. The coil is connected to a battery at time $t = 0$, so that a time-dependent current ${I_1}(t)$ starts flowing through the coil. If ${I_2}(t)$ is the current induced in the ring. and $B(t)$ is the magnetic field at the axis of the coil due to ${I_1}(t),$ then as a function of time $(t > 0)$, the product $I_2$ $(t) \,B(t)$
