7.12 Applications of ferrites

The various applications are described below:

1. Ferrites are used in thermal sensing switches used in refrigerators, air conditioners, electronic ovens, etc.
2. The magnetostrictive property of ferrites is utilized in producing ultrasonic waves from a ferrite rod by the application of an alternating magnetic field.
3. The insulating property of ferrites finds their use in electric motors; they are also used as flat rings for loud speakers, wind screen wiper motors and correction magnets for TV.
4. Some ferrites possess high rectangular hysteresis loop, so they are useful in the construction of computer memory system for rapid storage and retrieval of digital information.
5. Mixed ferrites possess high resistivity and good magnetic ...
