An inductor is a passive electronic component that can store energy in a magnetic field generated by an electric current passing through it. Usually this inductor is in the form of a conductor wire that is formed around a coil, this winding will help create a strong magnetic field in the coil. Another understanding states that this inductor is a basic electronic component used in circuits whose current and voltage vary due to the inductor's ability to process alternating current.
These inductors include devices of various uses, sizes and types, including components for surge power filters, radio wave control circuits, electric measuring circuits, and energy storage devices. Just like capacitors, inductors can also be classified into variable inductors, fixed inductors, and adjustable inductors. All inductors can be made with or without a magnetic core. An inductor without a magnetic core is called a coil air core, although the actual core material can be made of ceramic, plastic, or other nonmagnetic material. An inductor with a magnetic core is called a coil core iron.
The inductor winding has 2 types of winding, the first is the honeycomb ferrite coil. This winding is done by crossing to reduce the effect of distributed capacitance. And this coil is often used in tuning circuits on radio receivers in medium wave and long wave distances. Because of this winding construction, with a small winding shape, high inductance can still be achieved.
The second type of winding is the toroid core coil. This twist is quite simple where this winding is done by or like forming a cylinder. With a coil like this, the coil can create an external magnetic field with a north-south pole. This toroid coil can also be made into a donut shape, so that it can unite the north and south poles. In this toroid coil functions to hold the magnetic field on the coil. This can cause less magnetic radiation from the windings, and immunity from external magnetic fields.
This is a brief explanation of the inductor. May be useful for you all.
