2. Structure and composition
Chip inductors are a commonly used electronic component. When the current passes through the wire, a certain electromagnetic field will be generated around the wire, and the wire in this electromagnetic field will generate an induced electromotive force-self-induced electromotive force, which we call electromagnetic induction. In order to enhance electromagnetic induction, people often wind the insulated wire into a coil with a certain number of turns.
