Ferrite cylinders are widely used in speakers for home and car audio systems as they suppress high frequency noise in electronic circuits.
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.
With no moving parts the Ferrite pot requires no maintenance beyond ensuring the magnet is clean and has a long life.
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.
Any machining of Ferrite blocks must be done with a diamond wheel, ideally before magnetisation, as they are hard and brittle.
