Magnetization Direction

1) Permanent magnet supplied under two conditions, Magnetized or no magnetized, is usually not marked its polarity. If the user require, we could mark the polarity by the means agreed on. When pacing the order, the user should inform the supply condition and if the mark of the polarity is necessary.

2) The magnetization field of permanent magnet is related to the permanent magnetic material type and its intrinsic coercive force. If the magnet need magnetization and demagnetization, please contact with us and ask for technique support.
There are two methods to magnetize the magnet: DC field and pulse magnetic field.
There are three methods to demagnetize the magnet: demagnetization by heat is a special process technique, demagnetization in AC field, demagnetization in DC field. This asks for very strong magnetic field and high demagnetization skill.

3) Geometry shape and magnetization direction of permanent magnet: in principle, we produce permanent magnet in various shapes. Usually, it includes block, disc, ring, segment etc. The detailed illustration of the magnetization direction is below:


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
