Inductive energy storage constant current

Inductor

An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. [1] An inductor typically consists of an insulated wire wound into a coil.. When the current flowing through the coil changes, the time-varying magnetic field induces an electromotive force (emf) in the conductor

Energy Stored in Inductor: Theory & Examples

Energy in the inductor is stored in the form of a magnetic field. When current is applied, the energy of the magnetic field expands and increases the energy stored in the inductor. The energy remains constant as long as the current is maintained. If the current is removed, the energy is discharged as the magnetic field contracts.
