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 maximum lifting capacity specified above was measured using smooth, polished sheet metal. The sheet metal used was of optimal thickness. The pull-off force acted perpendicularly. With a force acting parallel to the sheet metal, i.e. when moving the magnet across the sheet metal, the lifting capacity of the magnet will be significantly lower. The gap between the magnet and the sheet metal resulting from the sheet metal being covered with a layer of paint or galvanic coating will also cause a decrease in the lifting capacity of the magnet. Any roughness or unevenness of the sheet metal will also reduce the lifting capacity of the magnet. The highest lifting capacity is achieved by using a sufficiently thick sheet containing a high amount of iron. Using high-carbon steel or cast iron sheet will result in a lower lifting capacity. The maximum lifting capacity is also affected by the operating temperature of the magnet. A heated magnet will have a lower lifting capacity.
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 specific maximum operating temperature of a magnet depends on the magnetic circuit in which it is placed, so we strongly recommend testing the magnet yourself under specific conditions. A heated magnet will have less adhesive force. 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.

Magnetic properties are not identical for every magnet. The results of measurements of different samples will vary, among other things, due to the inherent heterogeneity of the material and the measurement tolerances of the measuring device used. For measurements in accordance with IEC 60404-5, the measurement tolerances are ±1% for remanence induction Br and ±2% for coercivity HcB and coercivity HcJ. A magnet that is coated with nickel should have this coating removed before measurement, as the magnetic properties of nickel will affect the measurement result, underestimating the obtained parameter values. A zinc coating does not affect the measurement result.
Therefore, the parameter values given are approximate.
We can offer magnet parameters according to individual specifications, including for remanence induction Br, coercivity HcB, coercivity HcJ, magnetic moment, operating point Jd, magnetisation direction and its deviation, etc. In your e-mail correspondence, please indicate the required minimum parameter values or magnetic parameter values within the specified minimum-maximum range.

D6x2/N35 - tiny disc magnet
This tiny disc magnet is a neodymium magnet. Every neodymium magnet is a rare earth magnet.
Rare earth magnets contain at least some of the metals known as rare earth elements. These elements include scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium. The most well-known of these elements for any magnetism enthusiast is, of course, neodymium, as is samarium, which is used to produce SmCo magnets. It is generally believed that rare earth metals occur in small quantities in the earth's crust. In fact, there are quite a lot of them, but because their deposits are generally scattered and rare, and therefore not suitable for profitable industrial mining, they have been labelled ‘rare earth elements’.
