Neodymium Rod Magnet 3 x 30 mm N48
 
Neodymium (NdFeB) is among the strongest magnetic materials and provides substantial holding force for its size. Alongside high magnetic attraction, the surface coating helps improve durability. N48 indicates the magnetic grade, commonly ranging from N35 to N52; higher numbers generally indicate greater magnetic attraction. The cylinder magnet can be incorporated discreetly into components, holders or housings and is easy to align.
 
At Ø3×30 mm, this magnet is useful for magnetic catches, DIY, organisation and lighter attachments to steel. (Ø3×30 mm) Holding force depends strongly on the thickness and condition of the metal surface. It is greater on thick steel and weaker on thin sheet metal.
 
Warning: not suitable for children. Swallowed magnets can cause serious injuries. Seek urgent medical attention. Magnets can snap together quickly and pinch fingers. They are hard but brittle, so do not allow them to collide. Keep them away from bank cards, sensitive electronics and medical devices such as pacemakers.
