Mono-Pole Magnets and Single Pole Magnets

Mono-pole magnets (also called as single pole magnets) are the magnets that only one surface have magnetism, the other surface just has very weak magnetism. For example packing magnets used on moon cake boxes, mobile phone boxes, suitcases, leather etc. Then mono-pole disc magnets can lower the cost and save magnetic material.

How the NdFeB Mono-pole Magnets Are Made?

We all know there are at least two poles for one magnet. The method is coating one surface of the magnet with iron sheet. The magnetism of the coated surface is shielded, the magnetic lines are guided to the other surface, the magnetic force of other surface was strengthened. For some magnets application, only need the magnetic force of one side, the other side of magnetic force will cause interference; some application, only one side of magnetism can be used, the other side not used, which is not essential.

Key Factors of Magnetic Force Effect for Mono-pole Magnets

We can well use below principles to make the magnetic force of single pole magnets increased 50%. The maximum low cost and save material in the field of packing.
1. Material: material kind and thickness and the distance between magnets and iron coats have a close relation with magnetic power.The pure iron sheet is easy to lost magnetism, the refraction will be strengthened with special treatment.There is no 100% shielding material so far.
2. Angle of coats: the effect is the best for solitary form angle coats, while right angle coats will lose the more magnetic line.
3. Space: magnetic line is like mobile phone signal, it needs space to refraction.
