In this article we will discuss about Ferrites, Fundamental Theory of Ferrites and Gyroscopic Action. Introduction of Ferrites Ferrites are compounds of iron, zinc, manganese, magnesium, cobalt, aluminum, and nickel oxides. They are manufactured by pressing into shape the required mixture of the finely divided metallic oxide powders and then firing the shaped mixture at about 2000°F. The product is a ceramic with high electrical resistance. Ferrites behave as iron alloys at low frequencies, but at high frequencies their high electrical resistance prevents eddy currents, and resonance takes place within…
