Neodymium Ring Magnet 10 x 7 x 9 mm N48
 
A neodymium (NdFeB) ring magnet is very strong. It is magnetised in a strong magnetic field during manufacture, providing high magnetic attraction in a compact 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 ring shape is useful for mounting on a shaft or screw, or for precise alignment and guidance. The central hole helps with these applications.
 
At Ø10/Ø7×9 mm, this magnet is useful for magnetic catches, DIY, organisation and lighter attachments to steel. (Ø10/Ø7×9 mm) For best results, ensure direct contact with the surface. The magnet provides a particularly strong hold on solid steel.
 
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 bank cards, sensitive electronics and medical devices such as pacemakers.
