7.15: Magnetic Energy

When current is applied, the current-bearing elements of the structure exert forces on each other. Since these elements are not normally free to move, we may interpret this force as potential energy stored in the magnetic field associated with the current (Section 7.12). We now want to know how much energy is stored in this field.
