Ceramic Magnets
Ceramic magnets are comprised of a combination of iron oxide and strontium carbonate. Low cost, light weight, a relatively high energy product, and good resistance to demagnetization account for widespread use of ceramic magnets. Ceramic magnets have a max operating temperature of 480°F, which makes it a good choice for some high temperature applications. Common applications include; speaker magnets, motors, reed switches, and Hall-Effect devices.
