Meco N35 30x10x5mm Strong Block Magnet 4mm Hole Countersunk Rare Earth Neodymium Magnet

Description: N35 Strong Block Magnet 30x10X5mm Rare Earth Neodymium 2 Countersunk 4mm Hole Neodymium (chemical symbol Nd) is element 60 on the periodic table. It is a rare earth metal and forms one of the Lanthanides series. When added to Iron (Fe) and Boron (B) (chemical formula Nd14Fe21B) the resultant magnets are the strongest magnets currently available. Neodymium magnets are sometimes known as Neo, Neod or NIB magnets. Neodymium magnet are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting. Neodymium block magnet was made of NdFeB, have strong magnetic performances and appearance does not rust, usually placed in room temperature, the maximum operating temperature is 80 C and it never will demagnetization.
