Ferrite magnets are fabricated by calcining the mixture of iron oxide and Barium or Strontium carbonate to form a metallic oxide. Almost all of ferrite arc magnets are served to motor applications. As the core component of the permanent magnet direct current (DC) motor, ferrite arc magnets are widely used in the motors of automotive, household electrical appliance, and power tools. Ferrite magnets can be used up to 250 degrees Celsius besides superior corrosion resistance.
