Also known as ferrite magnets, ceramic magnets offer excellent value for money when pull strength is not the most important factor. They have a high resistance to corrosion and demagnetisation and can operate in temperatures up to 356 degrees Fahrenheit. Ring magnets are typically made for loudspeaker systems and their sizes have evolved with demand from this market. However, they are also commonly used in magnetic rollers for separating applications and in the printing industry. Because these magnets are weakly magnetized they are not suitable for weight-bearing applications, but instead are commonly used in sensors and other similar applications.
