A useful feature of these magnets is that they have only one adhesive surface, where the whole magnetic energy is focused. The magnetic field is limited by a shielded system, avoiding the magnetization of the surrounding objects.

Elastomer surface provides better adhesion while taking up smaller space. The adhesive force or the bond between the magnet and the surface is influenced by several factors:

- an air gap;
- roughness and shape of the surface;
- the temperature; and
- the content of magnetic-iron material in the steel or its volume.

⚠️ Handle with Care: While this magnet is robust, it's not intended for heavier objects. Weight limits vary based on factors like the thickness of ferrous metal, surface finish (paint), and the hanger's position. Use discretion for safe usage. Keep away from children. The maximum working temperature is 80℃.

For use on a flat surface, uneven surface or curved surface affects the adhesion.
