Disc magnet:
Disc magnets are thin flat circular magnets where the thickness does not exceed the diameter. They
are the most commonly used magnet shape and the most versatile. They are used in holding
applications where a hole is drilled and the magnet is recessed into the hole. They are commonly
used with cup assemblies to increase their holding strength.
