[0002] The magnetic core is a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical representatives of magnetic core materials. Manganese-zinc ferrite is known for its high magnetic permeability and high magnetic flux density, while showing low loss characteristics.
