Ferrite Magnets

Ferrite magnets are a type of ceramic compound derived from iron and oxide which can be both ferromagnetic and nonconductive which means that they can be both magnetised and attracted to a magnet. Ferrites are categorised into two families depending on their magnetic coercively (resistance to being demagnetised) these are hard ferrites and soft ferrites. Hard ferrites have a high coercively and common types include Manganese-zinc ferrite and Nickel-zinc ferrite. Soft ferrites have a low magnetic coercively and common types include Barium ferrite, Strontium ferrite and Cobalt ferrite. Ferrites, both hard and low ferrites, are used in loudspeakers, refrigerator magnets, small eclectic motors, inductors, transformers and various types of microwave components.
