## Ferrite magnetic ring online calculator

Ferrite is a metal oxide with ferromagnetism. In terms of electrical properties, ferrite has a much higher electrical resistivity than metal and alloy magnetic materials, and has a higher dielectric property. The magnetic properties of ferrite also exhibit high magnetic permeability at high frequencies. Therefore, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and low voltage.

The following calculator is a ferrite magnetic ring online calculator for the calculation of the number of turns of the ferrite magnetic ring inductance value.
