Height
5 [mm] +0,1/-0,1
magnetizing direction along dimension
5 [mm] parallel to height

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;.
Material
Neodymium
Grade
N42
Maximum working temperature
80 °[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].
Coating
Nickel (NiCuNi)

Sintered neodymium magnets are brittle (fragile). A neodymium magnet without housing could break after an impact with another strong magnet.
Weight
0,94 [g]

Magnetic properties of material grade N42: remanence Br 1,28-1,32 [T], coercivity HcB min. 923 [kA/m], coercivity HcJ min. 955 [kA/m], energy product (BH)max 318-342 [kJ/m3(Magnetic properties of a particular material, together with its shape, volume, max. working temperature and direction of magnetization have influence on practical magnetic properties of a magnet.)

Physical proprieties: density ~7,5 [g/cm3], Vickers’ hardness (HV) ~600 [kG/mm2], resistivity ~144 [uOhm x cm]

Max. working temperature is no more than 80°[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].

Direction of magnetization along the height means that one circular surface of a magnet makes the N-pole, while the other – opposite – circular surface refers to the S-pole.

Magnetic flux: ~ x 10-3 [mWb], for K(Helmholtz coil constant) = 1,14 × 10-4[m]

Magnetic moment: ~ x 10-3 [mWb] × 1,14 × 10-4[m] = ~ x 10-6 [mWb] × [m]

Magnetic field in geometrical center of surface of the magnetic pole, with a distance of 0,7 [mm] is ~0, [T]

Magnetic field next to the edge of surface of the magnetic pole (max.), with a distance of 0,7 [mm] is ~0, [T]

Pull force: ~ [kg]. The pull force was measured by using smooth 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. 

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.

Anticorrosive protection: coating Ni+Cu+Ni. Do not use in water.

Sintered neodymium magnets are brittle (fragile). A neodymium magnet without housing could break after an impact with another strong magnet.

Weight of the magnet: ~[g]

We recommend testing of a magnet sample in specific conditions.
