Ferrite cylinders are widely used in speakers for home and car audio systems as they suppress high frequency noise in electronic circuits.
Ferrite ring magnets are often used in loudspeakers and also in resonance imaging and torque drives. One popular application for children is the fishing game, tied on a piece of string to pick up pins and needles.
Ferrite disc magnets come in a variety of sizes, as a low cost magnetic material they are to be found across a broad range of magnetic therapeutic uses, on the back of three dimensional fridge magnets and in school science projects.
Large blocks of Ferrite magnet are often used in sweeping and separation applications. Smaller Ferrite blocks are commonly used in DC motors, as sensors and in various hand crafts.
Ferrite pot magnets have a mild steel casing over a Ferrite ring magnet with a round central hole for fixing a bolt, rivet or screw, through for attaching to non-magnetic surfaces.
