Super Strong Powerful Permanent Magnets Neodymium Magnet Bar 30x10x4mm Magnetic

Super Strong Powerful Permanent Magnets Neodymium Magnet Bar 30x10x4mm Magnetic Specifications: Product size: 30*10*4mm Product material: sintered Ndfeb Magnet coating: nickel copper nickel three layer treatment, good rust resistance, corrosion resistance. Performance grade: N35 Tolerance: Apporx ±0~±1mm Direction of magnetization: Thickness of magnetization (N S on two big faces) Max working temperature: 80 degrees celsius Precautions: Be careful, fragile, careful, keep it dry at room temperature Density: 7.34 (g/cm3) Material:Neodymium iron boron rare earth, currently on the strong magnetic material. In theory the suction is hundreds of times its own weight. Notice:1. Magnet is not iron, raw material rare earth Neodymium iron boron fired, is fragile, can not impact, due to its own suction so will not pay attention to when the suction, there is a collision, may be broken, so please pay attention to handle light!2. The characteristics of strong magnetic magnet are hard and brittle, especially the long and thin strips and the strong magnetic field with pore are fragile.When separating the magnet from the magnet, it is necessary to slide away slowly. After separating the magnet, the distance between the magnet and the magnet should be kept well. Otherwise, the magnet may be damaged by collision (cut off corners or break off) when absorbing each other. Instructions for Use of Strong Magnetism:1. Between strong magnetic or with other iron phase suction and separation, careful operation can not impact! Otherwise easy to cause damage or clip fingers;2. Ndfeb strong magnetic material is hard, brittle and with strong magnetic field. It should be taken lightly and put away.3. Strong magnetic suggested pushing stagger, must not hard lever, otherwise easy to cause a lack of Angle;4. Keep away from display, bank card, computer, TV, mobile phone, etc
