Artificial magnets: divided into a hoop magnet and a bar magnet, is the most common in our lives, of which magnet magnets more popular. Single-sided magnet refers to one side of the magnet, the other side of the magnetic weak magnet, the method is to use special treatment of galvanized iron double-sided magnet side wrapped, so wrapped side of the magnetic will be shielded, the magnetic force is refracted to the other side, The other side will be enhanced magnetic. If there are occasions where only one side of the magnetic, magnetic and if the other side will cause damage or interference; in some cases, such as the magnet on the box is only required to have a magnetic side, the other side of the optional, there is no magnetic useless, Using single-sided magnetism in this way greatly reduces costs and saves magnetic materials. The magnetic refraction of a single-sided magnet is the same as the refraction of a satellite dish or the refraction of light by a flashlight lamp:

1, material: the choice of materials and thickness, as well as the distance between the magnet and the material has a close relationship. Pure metal magnetic flux leakage easily, after special treatment refraction will be enhanced, but 100% shielding material has not been studied, but different manufacturers to do the material effect is also different.

2, point of view: According to the principle of refraction, the best effect of the arc material, rectangular material refractive loss greater.

3, space: magnetic lines in the air like a cell phone signal, you need to have space to refraction. Flashlight light pot, such as completely wrapped in the bulb, the use of effect is certainly not good, because there is a lot of light refraction loss.

How to use the above principle, the magnetic enhancement effect is the best, is the best between many parameters, many manufacturers are also repeated experiments, such as single-sided magnetic processing is the best result of 50% increase, so that in the packaging Box luggage and other fields will greatly reduce production costs and save magnetic materials.
