Performance parameters

External diameter

12 [mm] +0,1/-0,1


10 [mm] +0,1/-0,1

magnetizing direction along dimension

10 [mm]

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.



Magnet type


Maximal hoisting capacity

4,86 [kg]

The pull force was measured by using metal sheet 10 [mm] thick, acting with perpendicular detaching force. With the force acting on the sliding off, the lifting capacity of the magnet will be 5 times smaller. 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 surface

0,18 [T]


Nickel (NiCuNi)

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.

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].

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.
As an example, you will find attached a graph of a course of the II quadrant of magnetic hysteresis loop for a material grade N38.
