Power magnets are made of neodymium

The strength weakens the further the magnet is from the magnetic surface

is not a toy - you have to know what you are dealing with

Du kan også sætte magneterne på metal

where you erase like a blackboard - just be aware that dark board markers can leave shadows

Power magnet, Stav 4x12 mm. engros Power magnets are made ofNeodymium magnets Power magnets NdFeB Diameter: 0. 4 cm Length: 1. 25 cm Strength: approx. 0. 56 kg. A magnetic rod is magnetic at both ends. Therefore, it's easier to pick up than a flat magnet. This size is not suitable for magnetic glass boards (chat boards). SPECIFICATIONS: Strength: approx. 560 gr. Material: NdFeB Magnetisation: N42 Max. temperaturee: 80C Surface: nickel plated (Ni Cu Ni)
