Inductors store and release magnetic energy for various uses like filtering, energy storage, and impedance matching. Also called reactors, they are passive components with two terminals storing energy in their magnetic field and releasing it when needed. The unique shape of inductors produces a stronger magnetic field when current passes through, which resists alternating current but allows direct current flow while storing energy. They are categorized as Air core, Iron core, and Ferrite core components.
