Energy in a current carrying coil is stored in the form of

If a current flowing in a coil is reduced to half of its initial value,the relation between the new energy $(E_2)$ and the original energy $(E_1)$ stored in the coil will be

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 $H$)
