Performance parameters
Direction of magnetization along the height (the last dimension included in a magnet name) means that the surface of a magnet perpendicular to its height makes the N-pole, while the other surface perpendicular to the height 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 ~ 450°[C]. Temperature coefficient of remanence TK(Br): approx. -0,19 %/°[C]. Temperature coefficient of coercivity TK(HcJ): approx. 0,40 %/°[C].
Ferrite magnets do not require anticorrosive protection. They my be used in water.
As ceramic magnets, ferrite magnets are brittle.
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.

60x20x13,6/F35 - ferrite magnet
This is a plate magnet. It is rectangular in shape. Bar magnet
It is a ferrite magnet, magnetised along the height. It has two poles, which means it is double-sided. Ferrite magnets are well resistant to corrosion and do not require additional protection. It has been manufactured to excellent dimensional tolerances.
The maximum operating temperature is no more than 250 degrees Celsius.
Ferrite magnets stick to metal surface (ferromagnetic materials).
