$A$ $100\, mH$ coil carries a current of $1\, A$. The energy stored in its magnetic field is......$J$.

The magnetic potential energy stored in a certain inductor is $49 \ mJ$ when the current in the inductor is $70 \ mA$. The inductance of the inductor is (in $H$)

If a current of $4$ $A$ produces a magnetic flux of $3 \times 10^{-3}$ $Wb$ through a coil of $400$ turns, the energy stored in the coil will be: (in $J$)

Which of the following statements are correct?
$(a)$ An inductor stores energy in the form of a magnetic field.
$(b)$ $A$ capacitor stores energy in the form of an electric field.
$(c)$ An inductor stores energy in the form of both electric and magnetic fields.
$(d)$ $A$ capacitor stores energy in the form of both electric and magnetic fields.

$A$ coil of resistance $10 \, \Omega$ and an inductance $5 \, H$ is connected to a $100 \, V$ battery. The energy stored in the coil is:
