Common direction of magnetization showed in picture bellow:

The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off. Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
Common direction of magnetization showed in picture bellow:
1> Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametrically.
2> Rectangle shape magnets can be magnetized through Thickness, Length or Width.
3> Arc shape magnets can be magnetized Diametrically, through Width or Thickness.

 
Special direction of magnetization can be customized as required.

Coating and Plating

The anti-corrosion ability of NdFeB is very poor because the Nd-rich phase in sintered NdFeB is prone to oxidation, which eventually leads to the powder frothing of sintered NdFeB products, so the sintered NdFeB needs to be plated or coated with anti-oxidation layer to prevent the products from direct contact with the atmosphere.

The commonly used plating layers for sintered NdFeB are Zn, Ni, and NiCuNi, etc., which need to be passivated and plated before plating.
