Performance parameters
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.
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.
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].
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.

D22xd6x10/N38 - Neodymium magnet
This is a round magnet with a hole, a ring magnet, magnet with a through-hole, disc magnet with hole, cylindrical magnet with hole, toroid with a rectangular cross-section. It is a neodymium magnet, magnetised along the thickness 10 mm. It has two magnetic poles, which means it is double-sided. It has been protected against corrosion by nickel plating. It has been manufactured to excellent dimensional tolerances. The maximum operating temperature is no more than 80 degrees Celsius. Neodymium magnets stick to metal surface. You can attached magnet to surfaces made of ferromagnetic materials. This magnet is strong for its dimensions.
To say that neodymium magnets are strong and powerful does not do them justice. Neodymium magnets are the strongest and most powerful permanent magnets.
