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 ...
You can make ads in the Engineering ToolBox more useful to you! The energy stored in the magnetic field of an inductor can be calculated as. W = 1/2 L I2 (1) where. W = energy stored (joules, J) L = inductance (henrys, H) I = current (amps, A)

In a pure inductor, the energy is stored without loss, and is returned to the rest of the circuit when the current through the inductor is ramped down, and its associated magnetic field collapses. Consider a simple solenoid. Equations ( 244 ), ( 246 ), and ( 249) can be combined to give. This represents the energy stored in the magnetic field ...

Somewhere in that paper, they choose differently than I did above, saying that the inductor''s energy represents potential, and not kinetic, energy. But like I said, you get to choose. So I prefer to think of the Coulombs on a capacitor as position coordinates and the Webers of an inductor as momentum coordinates, which swaps those roles.
