Which term describes the energy stored in a magnetic field?

Explanation:
The energy stored in a magnetic field comes from inductance. When current flows through an inductor, a magnetic field builds up around it and stores energy, quantified by E = 1/2 L I^2. Inductance is that property that describes how much magnetic energy is stored for a given current. An inductor is the component that shows this behavior. Capacitance, on the other hand, relates to energy stored in an electric field (in a capacitor, E = 1/2 C V^2). Frequency is simply cycles per second, not energy, and reactive power describes how energy moves back and forth between source and reactive components rather than the stored energy itself.
