Ferrite Magnet for Speaker is sintered permanent magnet composed of barium or strontium ferrite.This class of magnet, aside from good resistance to demagnetization, has the popular advantage of low cost. Block ferrite magnets are very hard and brittle, and require specialized machining techniques.
Ferrite magnet has Anisotropic and Isotropic two type.
Anisotropic grades are oriented in the manufacturing direction, and must be magnetized in the direction of orientation. Have grade: Y8T Y10T.Isotropic grades are not oriented and can be magnetized in any direction. Have grade Y25,Y30, Y30BH ,Y35.
Because of their low cost, ferrite magnet has a very wide range as well as very large quantity of applications.
Applications of Ferrite Magnet for Speaker
- Speaker magnets
- DC brushless motors
- Magnetic Resonance Imaging (MRI)
- Magnetos used on lawnmowers and outboard motors
- DC permanent magnet motors (used in cars)
- Separators (separate ferrous material from non-ferrous)
- Used in magnetic assemblies designed for lifting, holding, retrieving and separating
