Hook magnets white neodymium
Distinctive feature: These hook magnets can be used to hang up objects. You can remove the hook. Thanks to the white powder coating, the magnet blends in perfectly on white walls and ceilings. Our hook magnets without coating are more noticeable but cheaper.
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, if you attach a pot magnet on the wall (for instance to hang up clothing), the magnet will slide down much faster than when you attach it on the ceiling.
Rust: These magnets are not rust-proof and therefore intended for dry indoor use.
