Performance parameters
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.
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.
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.

D6Ax2,5/N35H - Neodymium magnet
This disc-shaped neodymium magnet has been magnetised in an unusual way. It has an unusual magnetic polarity. One half of the cylindrical surface is the N pole and the other, opposite cylindrical surface is the S pole. The direction of magnetisation is indicated by the arrow in the sketch in the photo gallery.
