Ceramic ring magnets, also known as Ferrite Ring Magnets, come in a wide range of sizes. They are often used in loudspeakers and in resonance imaging and torque drives. Other applications for this permanent magnet include holding, door closures, joinery, and light fixtures. Ceramic Rings are similar to Ceramic Discs but with a hole in the middle, which makes them a versatile magnet option. One popular application is the fishing game, tied on a piece of string, or to pick up pins and needles. Ferrite magnets have less magnetic strength (due to the hole) but their inexpensive pricing makes them a customer favorite.
Ceramic magnets are manufactured using powder technology techniques, meaning they can easily be magnetized or attracted to a magnet. Ferrites can be divided into two families based on their resistance to being demagnetized (magnetic coercivity).
Ferrite compounds made of mostly rusted iron (iron oxide) are extremely low cost, have excellent corrosion resistance. They are very stable and difficult to demagnetize, can therefore be made with both high and low coercive forces. Yogoro Kato and Takeshi Takei of the Tokyo Institute of Technology synthesized the first ferrite compounds in 1930
Permanent ferrite magnets are made of hard ferrites, which have a high coercivity and high remanence after magnetization. The high coercivity means the materials are very resistant to becoming demagnetized, an essential characteristic for a permanent magnet.
For example, Ferrite cores are used in electronic inductors, transformers, and electromagnets where the high electrical resistance of the ferrite leads to very low eddy current losses, in addition they are commonly seen as a lump in a computer cable, therefore called a ferrite bead, which helps to prevent high frequency electrical noise (radio frequency interference) from exiting or entering the equipment.
