What describes the ability to store energy in a magnetic field?

Inductance is the physical property that allows a circuit or component, like a coil of wire, to store energy in the form of a magnetic field. When electrical current flows through an inductor, a magnetic field builds up around it, storing energy that can later be released back into the circuit. It is important not to confuse this with capacitance, which is the ability to store energy in an electric field rather than a magnetic field. Resistance, another common distractor, does not store energy at all; it simply dissipates electrical energy as heat.
