Neodymium Disc Magnet 6 x 5 mm N35
 
Neodymium (NdFeB) is among the strongest magnetic materials, even in small sizes, and its stability makes it useful for many practical applications. Neodymium is much stronger than ferrite, and its protective coating helps prevent corrosion. N35 indicates the magnetic grade; NdFeB grades commonly range from N35 to N52, with higher numbers generally indicating stronger magnets.
 
The Ø6 × 5 mm size is suitable for DIY projects, small holders, catches and temporary attachments to steel. Even a small gap caused by thick paint, tape or an uneven surface noticeably reduces holding force. It performs best on solid steel.
 
Warning: keep out of reach of children. Magnets can snap together suddenly, pinch skin and chip or break on impact. Handle them carefully when bringing them together or separating them. Keep them away from bank cards, hard drives, sensitive electronics and medical devices.
