Working Functions of Ferrite core and Magnetic Core?

The ferrite core is a variety of magnetic core from ferrite that has winded with electrical transformer and some other components like inductors. This is mostly preferred for high magnetic permeability combined with low electrical conductivity. The major reasons of using low losses occur in high frequencies that are extended to using RF transformers and inductors in applications like SMPS and ferrite loopstick antennas for receiving signals in AM radios..
