What is an inductor?

Inductance includes self-inductance and mutual inductance. The main function of the inductor is to isolate and filter the AC signal or form a resonant circuit with capacitors and resistors. Self-inductance is when a current flows through the coil, a magnetic field is generated around the coil. When the current in the coil changes, the magnetic field around it also changes correspondingly. This changing magnetic field can cause the coil itself to generate an induced electromotive force (the electromotive force is used to represent the terminal voltage of the ideal power supply of the active element), which is the self-inductance.
