ceramic magnets iron oxide

Hard ferrite magnets are a low cost permanent magnet composed of strontium carbonate and iron oxide. They are also known as ceramic magnets. Ceramic magnets are very resistant to becoming demagnetized because of high coercivity & remanence after magnetization. This is an essential characteristic for any permanent magnet.
