| As energy stored in a inductor=1/2*L*I^2 so if current decreases energy stored also decreases. |

| Inductor stores energy when current increases and gives stored energy when current through it decreases. |

Yes, you are right @Sumeet.
Energy = 1/2 (L * I^2). If current will decrease energy will also decrease. |
