What type of electrical component stores energy in a magnetic field?

An inductor is a passive electronic component that temporarily stores energy in a magnetic field when an electric current flows through it. This magnetic field is created around the wire as the current passes, and it fundamentally resists any sudden changes in the current flow. It is highly useful to contrast this with a capacitor, which stores energy in an electric field rather than a magnetic field. Remembering that inductors rely on magnetism while capacitors rely on static electricity is the best way to keep them straight on the exam. Resistors simply dissipate electrical energy as heat and cannot store it, while diodes are semiconductor devices that act like one-way valves for current.
