Question

In the following figure the circuit to the left has a switch that
at t = 0 s is switched and disconnects the battery from the circuit. The state depicted on the
figure is right after the switch, still t = 0. As the current decreases over time, the magnetic
flux through the circuit on the right (due to the long cable of the circuit on the left) changes
and induces an EMF on the right circuit. How much power is consumed by R2 as a function
of time.
The distance between the wire on the left and the closest wire on the right is r = 2.0 cm.
The size of the circuit on the right is noted on the figure.
