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 pull force was measured by using metal sheet 10 [mm] thick, acting with perpendicular detaching force. With the force acting on the sliding off, the lifting capacity of the magnet will be 5 times smaller. The air gap comprised between the metal sheet and a magnet causes reduction in the pull force.
For flat magnets and magnets mounted in the open magnetic circuit working temperature may be insignificantly lower. For high magnets and magnets mounted in the closed magnetic circuit working temperature equals max. working temperature for a given material. Curie’s temperature is ~ 310°[C]. Temperature coefficient of remanence TK(Br: approx. ~0,12 %/°[C]. Temperature coefficient of coercivity TK(HcJ): approx. -0,6 %/°[C].
All the numbers quoted were obtained as a result of tests with one specific item in a room temperature and are intended to serve for comparison of practical magnetic properties of magnets offered by the shop.

D6xd1,5x3/N35 - Neodymium magnet
This is a small 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, magnetized along the height. It has two 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. Despite its small dimensions, this magnet is strong.
To say that neodymium magnets are strong and powerful does not do them justice. Neodymium magnets are the strongest and most powerful permanent magnets.
