Permanent ferrite 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 automotive, home appliances,
industry controls, etc.
Applications:
DC motor
Permanent ferrite magnet DC motor
Speaker
Magnetron
Magnetor
Passive magnetic energy
Magnetic Door Catcher
Toys
Arts and Crafts
