Direction of Magnetization

Neodymium magnet(also called strong magnet) can be produced in different shapes and sizes. Each shape has
2 ~4 kinds of magnetization direction, including axially oriented, magnetized through thickness and length,
oriented through diameter, multi-pole oriented on outer surface ,multi-pole oriented on inside diameter, diametrical orientation and so on

Surface Coating

Neodymium magnets have poor resistance to corrosion. In order to protect the neodymium magnet from corrosion, usually, neodymium magnet will be plated.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking. Meanwhile, other options for coating are Color Zinc, Zinc, Epoxy resin, Silver, Gold, Tin, and so on.

Common Applications

Neodymium magnet are widely used in many fields, Industries,  Electronic, Automotive,
Energy conservation, Telecommunications, Office automation, as well as many other applications.

Magnet Glossary

Residual Induction( Br): The magnetic induction corresponding to zero magnetizing force in a magnetic material after saturation in a closed circuit; measured in gauss or tesla.
Coercive Force( Hcb): The value of demagnetizing force that reduces residual induction to zero. Measure of how permanent a magnet is; permanent magnets have a high coercivity. The intensity of a magnetic field needed to demagnetize a substance.The maximum coercive force, as measured on a saturated magnet, is proportional to the remanent flux density. See "flux density." It is expressed in oersteds or kiloAmps per meter (kA/m).
