Ferrite magnet (Ceramic magnet) is one of the most cost effective
magnetic materials. Composed of Barium or Strontium ferrite, these
materials exhibit good resistance to demagnetiztion, and are the
lowest cost materials available today. It has a fair to good
resistance toward corrosion and it can operate in moderate heat.
Ceramic magnet has low energy product and they are usually used in
assemblies containing mild steel. Sintered ferrite magnets are hard
and brittle and are extensively used in cars, home appliances,
fitness equipment, etc.
Applications:
DC motor
Speaker
MRI
Separators
Magnetron
Magnetor
Magnetic Door Catcher
Instrument and Meters
Toys
Arts and Crafts
