Classified:
According to the form of inductance: fixed inductance, variable inductance.
According to the nature of the magnetic conductor: air core coil, ferrite coil, iron core coil, copper core coil.
According to the work nature: antenna coil, oscillating coil, choke coil, trap coil, deflection coil.
According to the winding structure classification: single-layer coil, multi-layer coil, honeycomb coil, densely wound coil, indirect wound coil, unborn coil, honeycomb coil, random winding coil.
The coil is wound on an insulating tube by wires one circle by one circle. The wires are insulated from each other. The insulating tube can be hollow, or it can contain an iron core or a magnetic powder core.
Inductance coil is a device that uses the principle of electromagnetic induction to work. When a current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire of this electromagnetic field will induce the wire in the range of the electromagnetic field.
The electrical characteristics of inductance coils are opposite to that of capacitors, "passing low frequencies and blocking high frequencies". The performance index of the inductor coil is mainly the size of the inductance.
The self-induced electromotive force in the inductor coil always counterbalances the current change in the coil. The inductance coil has an obstructive effect on the alternating current.
