General Introduction Ferrite (ceramic) magnets (Hard ferrite magnet) were developed in the 1960's as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, ferrite magnets have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption. It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.
Besides industrial application, Ferrite magnets are widely use in Educational area. Formed: ceramic magnet, sintered ferrite magnet
Applications of Ceramic Magnets :
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
Magnetic Door
Catcher Instrument and Meters
Toys
Arts and crafts
Attributes of Ceramic Magnets
Least expensive material compared to alnico and rare earth magnets
High intrinsic coercive force
Available in simple shapes only due to manufacturing process
Lower service temperature than alnico, greater than rare earth
Lower energy product than alnico and rare earth magnets
