Hard ferrites magnets, which have a high coercivity and high remanence after magnetization. Iron oxide and barium
or strontium carbonate are used in manufacturing of hard ferrite magnets. The high coercivity means the materials are
very resistant to becoming demagnetized, an essential characteristic for a permanent magnet. They also have high
magnetic permeability. These so-called ceramic magnets are cheap, and are widely used in household products such
as refrigerator magnets. Ferrite cores are used in electronic inductors, transformers, and electromagnets where the high
electrical resistance of the ferrite leads to very low eddy current losses. They are commonly seen as a lump in a computer
cable, called a ferrite bead, which helps to prevent high frequency electrical noise (radio frequency interference) from exiting
or entering the equipment.
