Ferrite Magnets - Overview

The permanent ferrite magnet, also known as ceramic magnet, is composed of iron and barium or strontium oxides. It is charcoal gray in color and usually offered in the form of discs, rings, blocks, cylinders, etc. They are usually found in magnetic assemblies designed for lifting, holding, retrieving, and separating purposes. Although not as powerful as Rare Earth magnets, their high coercivity and relative low cost make them ideal for use in motors and high temperature motors.Operating a ceramic magnet above 250°C will begin to result in magnetic strength losses. Operating ceramic magnets in extreme cold (below -20°C) will also result in temporary to permanent losses.
