Simotec Ferrite Magnet
Manufacturer: Shimonishi Giken Kogyo Co., Ltd
Product name: Ferrite Magnet
Features
- Ferrite magnets are magnets made by turning iron oxide into fine powder, molding it, and sintering it.
- Anisotropic ferrite magnets are magnets that have strong magnetic force only in a specific direction.
- Anisotropic ferrite magnets are currently the most popular magnets, widely used for a wide range of purposes due to their reasonable price.
- – It has relatively stable magnetic properties and is resistant to rust.
- – When using in an environment below -30°C, care must be taken to prevent demagnetization at low temperatures.
- – It has low mechanical strength and is prone to breaking like ceramic, so care must be taken when handling it.
Purpose of use
・Motors, sensors, speakers, etc.
