5 X 5 X 2 / N38 – NDFEB (NEODYMIUM) MAGNET
PERFORMANCE PARAMETERS
Length5 [mm] +0,1/-0,1Width5 [mm] +0,1/-0,1Height2 [mm] +0,1/-0,1magnetizing direction along dimension2 [mm]
Direction of magnetization along the height (the last dimension included in a magnet name) means that the surface of a magnet perpendicular to its height makes the N-pole, while the other surface perpendicular to the height refers to the S-pole;.
MaterialNeodymiumGradeN38maximal hoisting capacity0,63 [kg]
The pull force was measured by using metal sheet 10 [mm] thick, acting with perpendicular detaching force. The air gap comprised between the metal sheet and a magnet causes reduction in the pull force.
Magnetic field in geometrical center of the magnetic pole surface0,27 [T]Maximum working temperature80 °[C]
For flat magnets and magnets mounted in the open magnetic circuit working temperature may be insignificantly lower. For high magnets and magnets mounted in the closed magnetic circuit working temperature equals max. working temperature for a given material. Curie’s temperature is ~ 310°[C]. Temperature coefficient of remanence TK(Br: approx. ~0,12 %/°[C]. Temperature coefficient of coercivity TK(HcJ): approx. -0,6 %/°[C].
CoatingNickel (NiCuNi)
Sintered neodymium magnets are brittle (fragile). A neodymium magnet without housing could break after an impact with another strong magnet.
Magnetic moment56,544 [nWb]x[m]Weight0,38 [g]
All the numbers quoted were obtained as a result of tests with one specific item in a room temperature and are intended to serve for comparison of practical magnetic properties of magnets offered by the shop.
