Fixed Inductors are widely used in modern electronics applications. In particular, they are typically used in power circuits, switching power converters, and other high-power applications. The purpose of a fixed inductor is to store energy by generating a strong magnetic field in a relatively small space. This allows a circuit to store energy in the form of an induced magnetic field and retrieve it again when needed.

The most common type of fixed inductor is the air core inductor. Air core inductors are constructed from a simple coil of wire. This coil stores energy as a magnetic field, which is generated through the passage of current in the coil. Because the coil is a simple, non-magnetic material, this magnetic field can be retrieved and released as needed.

In some cases, a ferromagnetic core is used instead of an air core. A ferromagnetic core is a piece of material which is highly magnetic. When current is passed through this core, it will become magnetized and will store a large amount of energy. The same effect can be achieved with an air core, however, a ferromagnetic core will provide a much more efficient way of storing energy than an air core.

One of the most common applications for fixed inductors is in switching power converters. Switching power converters are used to convert a high voltage AC input into a low voltage DC output. This conversion is typically performed in a circuit which contains a number of inductors, each of which is used to store energy in the form of a magnetic field. When the input voltage is applied, the stored energy will be released back into the circuit to power the output device.

Other applications of fixed inductors include power supplies, battery chargers, and radio transmitters. They can also be used in a variety of signal processing applications, such as audio and video. Additionally, fixed inductors can be used in computers to provide a stable power supply, as they tend to be very efficient at storing energy.

Fixed inductors are usually rated according to their inductance, which is measured in henries. Inductance is a measure of the amount of energy that can be stored in the inductor and is proportional to the number of turns in the windings and the permeability of the core material. The most common range of inductance for fixed inductors is 6000-27000 henries, but higher values up to 500000 henries can be achieved with special materials.

The working principle of the fixed inductor is related to the concept of electromagnetic induction. Electromagnetic induction is a process in which a changing magnetic field can generate an electrical current or voltage in a conductor. When an electrical current passes through the coil of a fixed inductor, it creates a changing magnetic field. This changing magnetic field induces a voltage in the coil, resulting in the storage of an electrical charge. This stored charge can then be tapped and retrieved as needed.

The ability of a fixed inductor to store and release energy makes it an indispensable component in many modern electronics applications. By understanding the principles of fixed inductors, it is possible to make use of their unique capabilities to design efficient and reliable circuits.
