Magnetization Direction
Isotropic magnets, such as Bonded NdFeB Magnet, are unoriented and have no preferred direction; therefore it is possible to magnetize them in any direction. Almost all other materials are anisotropic and have a preferred direction of magnetization. They will exhibit the best magnetic properties when magnetized in the direction of the grain. Higher magnetic flux densities can be achieved with anisotropic magnets that are magnetized in their direction of orientation than with isotropic magnets.Magnet can be magnetized to the following direction of magnetization typically. AO Manget can supply in magnetized state or de-magnetized state (Demagnetizing Curve) according to customer's requirement.
The magnetization patterns for your project can be created with the following orientations:
 |
 |
 |
oriented through thickness |
axially oriented |
axially oriented in segments |
 |
 |
 |
oriented laterally multi-pole on one face |
multi-pole oriented in segments on outside diameter* |
multi-pole oriented in segments on one face |
 |
 |
 |
radially oriented* |
oriented through diameter* |
multi-pole orientation segments on inside diameter* |
 |
 |
　 |
radially oriented* |
diametrical oriented |
　 |
*only available in isotropic and some anisotropic materials only
The above outline shows typical magnetization patterns. We also provide custom magnetization. Please note that Uni-Pole or multi-poles Radia Oriented ring on Rare Earth magnets is also available.
Helpful notes: Axial magnetization is in the same direction that the magnet was oriented or pressed during its process, this could be expressed as: Magnetized through the thickness or axially magnetized. Radial magnetization is with one polarity on the inside of the ring magnet and an opposite polarity on the outside of the ring or arc segments. This form of magnetization is mostly used for ring or arc segment magnets.
