The graph in Fig. The induced current will be directed so as to produce a magnetic field that is upward through the smaller loop, in the same direction as the field of the larger loop. We do not employ energy conservation since, in reaching equilibrium, some energy is dissipated either as heat or radio waves. Thus, the middle two values quoted in the problem must correspond to the individual capacitors. We find the current from Eq.
