Uses of Inductor: Learn Definition Functions, And Applications
Energy Storage: One of the key functions of an inductor is to store electrical energy in its magnetic field. When current flows through an inductor, a magnetic field is generated around it. This magnetic field stores energy, which can be later released back into the circuit when the current changes or stops flowing.

Thus, the energy stored by the inductor increases only while the current is building up to its steady-state value. When the current remains constant, the energy stored in the magnetic field is also constant. Although no additional energy is stored by the inductance of the practical inductor, the resistance of the inductor dissipates energy at a ...
