A ceramic ring magnet is a laboratory apparatus that consists of a small, circular magnet made of ceramic material, typically composed of strontium ferrite. Ceramic magnets are known for their high resistance to demagnetization and their strong magnetic fields.
Ceramic ring magnets are commonly used in a variety of laboratory and industrial applications, such as motors, sensors, and generators. They can be used to create a magnetic field that can attract or repel other magnets, or to convert electrical energy into mechanical motion.
In laboratory settings, ceramic ring magnets are often used in experiments involving magnetism, electromagnetism, and magnetic fields. They are also used in scientific research, such as in studies of magnetic materials and magnetic properties of materials.
