Pot magnets with ferrite magnets

Pot magnets with ferrite magnets These magnets can be fastened with a countersunk screw. They are ferrite and not neodymium magnets like the otherwise identical countersunk pot magnets. They have therefore a lower adhesive force and are larger. But they are cheaper than neodymium magnets and can be used outside as well. We also carry screw-on neodymium magnets without pot.

Features of ferrite pot magnets

Principle: The strong neodymium magnets are embedded in a steel pot. The steel pot increases the adhesive force of the magnet on direct contact with a thick iron surface. If there is no direct contact with the counterpart, or if the steel plate is thin, painted or rough, you can strain it much less.

Shear force: The indicated adhesive force was measured perpendicular to the surface to which the magnet should stick. It takes a lot less strength to move the magnet sideways. Therefore, you can strain a pot magnet much less if you use it on a wall as opposed to using it on the ceiling.

Rust: These magnets are rust-proof and can therefore be used outdoors and in wet surroundings. The pots around the magnets, however, may build up a rust film over time.
