When a current of $4 \ mA$ passes through an inductor,if the flux linked with it is $32 \times 10^{-6} \ T \ m^2$,then the energy stored in the inductor is

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

$A$ coil has an inductance of $2 \, H$ and resistance of $4 \, \Omega$. $A$ $10 \, V$ potential difference is applied across the coil. The energy stored in the magnetic field after the current has built up to its equilibrium value will be $.......... \times 10^{-2} \, J$.

If the current through an inductor increases from $2 \ A$ to $3 \ A$,the magnetic energy stored in the inductor increases by: (in $\%$)

The magnetic potential energy stored in a certain inductor is $64 \times 10^{-3} \ J$,when the current in the inductor is $80 \ mA$. The inductance of this inductor is: (in $H$)

The magnetic energy stored in an inductor of inductance $5 \mu H$ carrying a current of $2 \ A$ is
