Which Type Of Inductor Core Material Is Likely To Produce The Least Inductance

Ferro magnetic or iron core inductors. The core must be large enough in size and low enough in permeability to avoid saturation or shift in inductance below the minimum required level these factors increase the turns and length of copper required causing wire loss to become an issue.

In this type of inductor core is completely absent.

Which type of inductor core material is likely to produce the least inductance. The lack of a metal core results in very little distortion but by the same token the coil must be very long to carry high amounts of inductance resulting in a large inductor. A well designed air core inductor may have a q of several hundred. One way is by using a physically larger air core inductor.

Basically they fall into general categories. Inductors are made in a variety of shapes and sizes. Both fixed and variable inductors can be classified according to the type of core material.

These are used in high frequency applications including tv and radio receivers. The air core inductors have larger coils to produce higher flux densities. A magnetic core can increase the inductance of a coil by a factor of several thousand by increasing the magnetic field due to its higher magnetic.

High q inductors must avoid saturation. Steel core inductor for low resistance high inductance applications steel cores are a step above air cores. A large dc inductor is often limited by the cores saturation point.

Three common types are the air core the iron core and the ferrite core. The main advantage of this type of inductors is that due to the circular shape symmetry is achieved in the whole shape of the inductor. These inductors have a magnetic material as the core substance to which the wire is wound.

These inductors offer high reluctance path for the magnetic flux hence less inductance. At vhf or higher frequencies an air core is likely to be used. These are in circular ring shape just as shown in the following figure.

The core material is chosen for best results for the frequency band. Ferromagnetic core or iron core inductors use a magnetic core made of a ferromagnetic or ferrimagnetic material such as iron or ferrite to increase the inductance.
