The magnetic field at the earth's surface can vary in response to solar activity. During one intense solar storm, the vertical component of the magnetic field changed by 2.8 μT per minute, causing voltage spikes in large loops of the power grid that knocked out power in parts of Canada What emf is induced in a square 170 km on...

An Inductor has an inductance 25 mH. 8 identical Inductors are then constructed in series. This network of Inductors is then connected to a 6.0 V cell, of internal resistance 4.0 Ω. How much energy is stored within the magnetic fields of these inductors (in total) when the current has reached a steady value? Express your answer in mJ.
