The magnetic refraction of the single -sided magnet is like the refraction of the signal or the refraction of the light on the signal of the satellite pot. The refractive effect is mainly determined by the following three aspects: 1. Materials: material selection and thickness, and the distance between the magnet and the material is closely close to Relationship. Pure iron skin is easy to leak magnetic. After special treatment, the refraction will be enhanced, but the 100%shielded materials have not yet been studied, but the effects of materials made by different manufacturers are also different. 2. angle: According to the principle of refraction, the arc material is the best effect, and the refractive loss of right -angle materials is large. 3. Space: The magnetic line is like a mobile phone signal in the air, which requires space to refract. If the firecracker cooker is completely wrapped on the lamp gun, the effect is not good, because a large amount of light refraction is lost. How to use the above principles, the best effect of enhancing magnetism is the best problem between many parameters. In this way, it will greatly reduce production costs and save magnetic materials in the fields of packaging boxes.
