Neodymium Rod Magnet 4 x 10 mm N48
 
NdFeB (neodymium) magnets provide high magnetic attraction for their size, making them popular for technical and DIY applications. 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.
 
The Ø4×10 mm cylinder is useful for DIY projects, including lids, boxes, small holders and quick attachments. (Ø4×10 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: keep away from children. Swallowing magnets can be life-threatening. Seek immediate medical attention if swallowing is suspected. Magnets can snap together suddenly, pinch skin and chip or break on impact. Separate them by sliding them apart. Keep them away from medical devices, cards and sensitive electronics.
