Artificial magnet

Artificial magnets: divided into hoof magnets and bar magnets, which are the most common in everyone's life, among which hoof magnets are more popular. A single-sided magnet refers to a magnet with magnetic on one side and weaker magnetic on the other side. The method is to wrap one side of the double-sided magnet with a specially treated galvanized iron sheet, so that the magnetism of the wrapped side will be shielded and the magnetic force will be refracted to the other side. On the other side, the magnetism will be enhanced. If there are occasions, Permanent magnet supplier  only one side needs to be magnetized, and if the other side is magnetized, it will cause damage or interference; in some occasions, for example, the magnet on the package box only needs to have magnetism on one side, and the other side is optional. It is useless if there is magnetism. In this way, the use of single-sided magnets will greatly reduce costs and save magnetic materials. The magnetic refraction of a single-sided magnet is determined by the refraction of the signal by a satellite pan or the refraction surface of the light by a flashlight pan:
1. Material: The choice and thickness of the material are closely related to the distance between the magnet and the material. Pure iron sheets are prone to magnetic leakage, and refraction will increase after special treatment, but 100% shielding materials have not been studied yet, but the effects of materials made by different manufacturers are different.
2. Angle: According to the principle of refraction, curved materials have the best effect, and right-angled materials have greater refraction loss.
3. Space: The lines of magnetic force in the air are like mobile phone signals, and they need space to be refracted. If the flashlight pot is completely wrapped on the bulb, the use effect is definitely not good, because a lot of light refraction is lost.
How to use the above principles to maximize the effect of magnetic enhancement is a question of seeking the best among many parameters. Many manufacturers are also doing repeated experiments. For example, the best result of single-sided magnetic treatment at Xi’an Guotai Magnet Factory is 50% enhancement. , This will greatly reduce production costs and save magnetic materials in areas such as packaging boxes and bags.
