Ferrite ring magnets
Ferrite ring magnets are ceramic magnets made primarily from iron oxide mixed with barium or strontium carbonate. These magnets are shaped into rings, featuring a central hole which enhances their versatility in various applications. Known for their good resistance to demagnetization and excellent corrosion resistance, ferrite ring magnets maintain stability under a broad range of temperatures and environmental conditions.
Their ring shape is particularly advantageous in applications requiring a central mounting point or the concentration of magnetic fields along the ring’s circumference. This makes them ideal for use in loudspeakers, motors, and various assemblies where they can be utilized for their magnetic properties without interfering with internal components.
Produced through a sintering process, these magnets are cost-effective and durable, making them suitable for both industrial and consumer applications. Despite not possessing the high magnetic strength of rare earth magnets, ferrite ring magnets are frequently used in educational projects and appliances, providing a reliable and economical solution for generating a magnetic field where extreme strength is not necessary.
