Performance parameters

Length

42,5 [mm] +0,1/-0,1

Width

20,5 [mm] +0,1/-0,1

Height

12 [mm] +0,1/-0,1

magnetizing direction along dimension

12 [mm]

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;.

Grade

N38

Magnet type

Neodymium

Maximal hoisting capacity

24 [kg]

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.

Magnetic field in geometrical center of the magnetic pole surface

0,35 [T]

Maximum working temperature

≤ 80 [°C]

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].

Housing

stainless steel, AISI 304 / EN 1.4301, approved for contact with food

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.

Waterproof

class IP67

Weight

100 [g]

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.
Physical properties

Density

~7,5 [g/cm3]

Vickers’ hardness (HV)

~600 [kg/mm2]

Resistivity

~144 [uOhm x cm]

A cased ferrite magnet may be used both for educational purposes as well as in research and laboratory experiments. It can also be used to construct permanent magnetic circuits. For a long durability provides the welded and waterproof housing made of acidproof steel ASI304, whereby the magnet is protected from both direct impacts and chemicals. In addition, the steel AISI304 is approved for contact with food, what enables the use in the food industry. There are permanently laser made markings "N" and "S" on both magnetic poles surfaces.

On commission we are ready to encase for you any NdFeB, ferrite, AlNiCo or SmCo magnet.

The maximum working temperature is: 80 [°C].
The maximum pull force is: ~ [kg].
The maximum magnetic field on is: ~350 [mT]

On the housing a thread, handle or eye can also be mounted.
