Inductor
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 an electromotive force (emf) in the conductor

Self Inductance
Self-inductance is the property of the current-carrying coil that resists or opposes the change of current flowing through it. This occurs mainly due to the self-induced emf produced in the coil itself. In simple terms, we can say that self-inductance is a phenomenon where there is the induction of a voltage in a current-carrying wire.
