Ceramic magnets, also known as ferrite magnets, are made from a mixture of iron oxide and other metallic elements. They are popular due to their low cost, resistance to corrosion, and ability to maintain their magnetic properties over time. These magnets are commonly used in various applications, including refrigerator magnets, loudspeakers, and electric motors. The manufacturing process involves sintering the powdered materials at high temperatures, which creates a hard, brittle material. Ceramic magnets are typically less powerful than other types, such as neodymium magnets, but their stability and affordability make them a preferred choice for many everyday uses.
