Record the inductance as l and the 20 turns as n calculate the al value of the ferrite inductor. Air gap will vary the inductance i think.

Types Of Inductors And Applications

Ferrites provide an excellent core material for a bead inductor.

How to make inductor ferrite core. At low frequencies ferrite bead inductors act as a normal inductor. The size and type of the core has to do with core loss power loss in the core. Make a simple ferrite inductor by wrapping at least 20 turns of wire around a ferrite rod.

To begin coiling your inductor you should take the drill bit or other cylindrical object and pinch it between your thumb and forefinger. The inductance of an inductor is directly proportional to the material and area of the core. You can insert a ferrite into an air core one and turn it into a ferrite core one somewhat.

Core is used in the inductors to make them compact and with fewer turns of wire. Low frequency such as 60 120hz should use laminated core. Check out this blog to make your own.

The type of core has a lot to do with the frequency current and power. You will have to find the number of turns of the coil. In ferrite core ones the coil is wound onto the core so it would not be loose.

The purpose of the material is to provide permittivity greater than air. This is a very very basic way to choose a core. One can determine the smallest core size assuming a winding factor of 50 and wire current carrying capacity of 500 circular mils per ampere.

With your other hand intersect the wire and the drill bit so that they form a cross with a majority of the wire being on one side. Suppose you want to make an inductor which produces an inductance of 10 mh. High frequency 1khz 1mhz should use a ferrite core.

Ferrite bead inductor basics. I suggest you stick with it. You teacher gave you the requirements.

Using an inductance meter measure the inductance of that rod. For switching regulators power materials are recommended because of their temperature and dc bias characteristics. Ferrite bead inductors form very effective filters for applications such as reducing electromagnetic interference because of the properties of the ferrite using within the inductor.

Thus the number of turns of the coil will be 26. The diameter of the coil is 1 inch and the coil length is given by 125 inches. By adding air gaps to these ferrite shapes the cores can be used efficiently while avoiding saturation.

These core selection procedures simplify the design of inductors for switching regulator applications.
