Performance parameters

External diameter

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

Height

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

Magnetizing direction along dimension

1 [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.

Grade

N38

Magnet type

Neodymium

Maximal hoisting capacity

0,09 [kg]

The magnetic force value given above, expressed in kilograms, was measured under ideal conditions. A thick iron plate with a smooth, unpainted surface was used. The force required to detach the magnet from the plate was perpendicular to the plate.

Magnetic field in geometrical center of the magnetic pole surface

0,18 [T]

Coating

Nickel-plated (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]

The maximum operating temperature of a magnet depends on the specific magnetic circuit in which the magnet is placed. Curie’s temperature is ~ 310°[C]. Temperature coefficient of remanence TK(Br): ≤ -0,12 %/°[C]. Temperature coefficient of coercivity TK(HcJ): ≤ -0,6 %/°[C].

Weight

0,05 [g]

The magnet parameter values presented here are the result of measurements taken on one specific magnet and are used to compare magnets available in the online shop. We recommend testing the magnet yourself under the expected operating conditions.
Magnetic properties of material grade N38

remanence Br

~1,21 [T]

coercivity HcB

min. 876 [kA/m]

coercivity HcJ

min. 955 [kA/m]

The magnetic properties of the material are not identical for every magnet. The measurement results for different magnets will vary due to the inherent heterogeneity of the magnetic material and the measurement tolerances of the measuring device.
Physical properties

Density

~7,5 [g/cm3]

Vickers’ hardness (HV)

~600 [kg/mm2]

Resistivity

~144 [uOhm x cm]

D3x1/N38 - miniature magnets



Miniature magnets with a diameter of 3 mm and a thickness of only 1 mm are often used in DIY projects. The maximum safe working temperature of this magnet is 80 degrees Celsius. Neodymium magnets lose their magnetic properties at high temperatures. The higher the temperature, the lower the magnetic force. The magnet is completely demagnetised when heated above the Curie temperature. Therefore, neodymium magnets should not be heated, not even for a short time.
