Economic Hard Ferrite Hobbies Magnet Dimension

Ceramic ring magnets, also known as Ferrite Ring Magnets, come in a wide range of sizes. They are often used in loudspeakers and in resonance imaging and torque drives. Other applications for this permanent magnet include holding, door closures, joinery, and light fixtures. Ceramic Rings are similar to Ceramic Discs but with a hole in the middle, which makes them a versatile magnet option. One popular application is the fishing game, tied on a piece of string, or to pick up pins and needles. Ferrite magnets have less magnetic strength (due to the hole) but their inexpensive pricing makes them a customer favorite.  4 Inch Dia Grade 8 Ceramic Ferrite Ring Magnet for Science Experiment
