Neodymium Disc Magnet 8 x 2 mm N35
 
Neodymium (NdFeB) is among the strongest magnetic materials, even in small sizes, and its stability makes it useful for many practical applications. It is noticeably stronger than conventional ferrite magnets and generally has a protective coating because the material is prone to corrosion. The N35 magnet belongs to the NdFeB family, commonly ranging from N35 to N52; a higher number generally means greater magnetic attraction.
 
At Ø8 × 2 mm, this magnet provides a good hold on metal and is useful at home, in workshops and for a variety of projects. The metal material and thickness strongly affect performance. A thicker, flatter surface gives a better hold.
 
Warning: keep away from children. Two magnets can snap together quickly, pinch fingers and crack or chip. Use spacers for storage and take care when separating them. Keep them away from medical devices and objects sensitive to magnetic fields, including cards and electronics.
