Neodymium Magnetic Sphere 14 mm N40
 
The magnetic sphere made from neodymium (NdFeB) is a small but very strong magnet, produced from a special alloy and magnetised in a high-intensity magnetic field. N40 indicates the magnetic grade. A higher value generally indicates a stronger magnet.
 
This 14 mm size is useful for DIY, organisation, quick tests and compact DIY projects. It performs best in direct contact with thick steel. Holding force may decrease on thin materials.
 
Warning: keep away from children. Swallowing magnets poses a serious danger and may require immediate medical intervention. Their strong attraction means they must be brought together and separated carefully to avoid pinching injuries or chipping.
