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 $\mathrm{I}_1(\mathrm{t})$ starts flowing through the coil. If $\mathrm{I}_2(\mathrm{t})$ is the current induced in the ring. and $B(t)$ is the magnetic field at the axis of the coil due to
$\mathrm{I}_1(\mathrm{t}) ,$ then as a function of time $( \mathrm{t}>0 ),$ the product $\mathrm{I}_2(\mathrm{t}) \ \mathrm{B}(\mathrm{t})$
