pot magnet works by attaching itself to ferromagnetic materials with the assistance of its magnetic flux, or to non-ferromagnetic materials with the assistance of fittings (such as studs and threaded holes) on the highest of its steel shell.

The steel shell on a pot magnet means it can hold a greater amount of ferromagnetic material. this is often because the steel pot causes the magnetism to be contained within the shell on the ferromagnetic surface, making the magnetic pull stronger.

This is as compared to a horseshoe magnet or magnet where the magnetic flux lines are splayed around the magnet and aren't focused on the surface the magnet is attaching itself to.

As the magnetic flux is concentrated in one area, the magnet won't be allowed to draw in ferromagnetic materials over an outsized air gap. this is often because the magnetic flux lines won't stretch out beyond the edges of the shell.

The pull force of a pot magnet attracts the ferromagnetic material to the magnet, holding it in situ. The larger the pull force of the pot magnet, the more material it can attract.

A magnet’s pull force is decided by a variety of various factors; for instance, how the magnet has been coated and any damage which can have occurred to the surface of the magnet.
