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.

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

D5x10/N38 - Neodymium rod magnet
A neodymium magnet strongly attracts iron and all its alloys, as well as gadolinium, nickel, erbium, cobalt and dysprosium. Whether a metal object is attracted more or less strongly also depends on its shape. In a long object, such as an iron nail, when it is saturated with a magnetic field, the positions of the magnetic poles quickly stabilise. The ‘N’ pole is at one end of the nail and the ‘S’ pole at the other. If we melt this nail at a high temperature and form the resulting material into a sphere, it will be more difficult to attract this sphere with a magnetic field, especially if the sphere is in motion. In this high magnet with a diameter of 5 mm and a height of 10 mm, the N pole is located on the circular base of the cylinder and the S pole on the opposite, also circular surface.
