The energy stored in a coil of inductance $L$ carrying a steady current $i$ is in the form:

The expression for the magnetic energy per unit volume stored in a solenoid in terms of magnetic field is . . . . . . .

The expression for the magnetic energy stored in a solenoid of length $L$, in terms of magnetic field $B$ and area $A$ is

Energy stored in a coil of self-inductance $40 \, mH$ carrying a steady current of $2 \, A$ is.....$J$

The magnetic energy stored in an inductor of inductance $4 \ H$ carrying a current of $1.5 \ A$ is

If the current of $I$ gives rise to a magnetic flux $\phi$ through a coil having $N$ turns,then the magnetic energy stored in the medium surrounding the coil is
