Ferrite disc magnets
Ferrite disc magnets are composed of ceramic materials primarily made from iron oxide combined with strontium or barium carbonate. These magnets are shaped into discs and are recognized for their excellent resistance to demagnetization and corrosion, making them highly durable. They also exhibit good temperature stability, capable of operating effectively across a range of environmental conditions.
The disc shape of these magnets allows for a focused magnetic field along the plane of the disc, which is beneficial for applications requiring surface-to-surface contact, such as in closures, sensors, and speakers. Manufactured through a sintering process, ferrite disc magnets are economical to produce and offer a balance of performance and cost, which makes them particularly attractive for educational and low-cost industrial applications.
Ferrite disc magnets are frequently used in crafts, home improvement projects, and educational settings where a moderate level of magnetic strength is sufficient. Their widespread use in various consumer products and devices highlights their versatility and reliability in everyday applications.
