N50 Strong Block Cuboid Rare Earth Neodymium Magnets 30x20x10mm

Description:N50 Strong Block Cuboid Rare Earth Neodymium Magnets 30mm x 20mm x 10mm N50Neodymium (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 magnets 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.Please be care when break apart because Neodymium block magnet have strong Magnetism.Specifications: Shape: CuboidMagnetic face: 30mm x 20mm (Length * Width )Thickness: 10mmGauss: 3000 gaussPull: about 5kgGrade: N50Plating: Ni-Cu-Ni ( Nickel )Material: NdFeBColor: SilverWeight: 43gQuantity: 1pcApplications:Acoustic Field: the speaker, receiver, microphone, alarm, stage audio, car audio and so on.Electronics: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter, meter, sound meter, a reed switch, sensors.Electrical Field: VCM, CD / DVD-ROM, generators, motors, servo motors, micro-motors, motors, vibration motors.Machinery and Equipment: magnetic separation, magnetic crane, magnetic machinery.Healthcare: MRI scanners, medical eq
