Ferrite capped pot magnets house a ceramic ferrite disc within a steel cup, concentrating the magnetic field at the working face to dramatically increase holding force compared to a bare ferrite disc of the same size. The steel shell protects the relatively brittle ferrite core from chipping and mechanical shock. Used for holding, clamping, and tooling fixtures in light industrial and educational settings, ferrite capped pots are a cost-effective solution where moderate holding force and durability are both required.
