Many people know magnets and learn how to use them. They also know that magnets are widely used in society. So, how do magnet manufacturers deal with magnets? Here are some measures taken by Yutong magnet manufacturers for magnets.
1. The magnet loses its magnetism. Magnet manufacturers use external magnetic fields to align the electrons in iron and cobalt ferromagnetic materials side by side, so that the magnetic effect that occurs is the same as the direction of the external magnetic field, so that magnetism will occur. The electrons in materials such as copper, aluminum, and lead are disordered and cannot produce magnetism. For example, when a magnet attracts an iron nail, it is because the magnetic field of the magnet magnetizes the iron nail, and then attracts each other. As a result, the iron nail is attracted by the magnet. If you want the magnet to lose its magnetism, just burn the magnet red. When the temperature of the magnet increases, the internal molecules of the magnet will speed up, resulting in chaotic movement of the electrons inside. When the temperature reaches a certain height, the direction of electron movement is completely disrupted, and the magnetism is naturally gone.
2. Shield the magnetic field. Magnet manufacturers deal with it by using ordinary iron plates. We all know that in order to meet the requirements of magnetic shielding, iron-nickel alloys such high magnetic permeability materials are generally used. If you are in an environment with a strong magnetic field that needs to be shielded, using only a single layer of material will have no effect. Generally, the thickness of the material is increased. In fact, the most effective method is to shield by combination, so that the magnetic field can be minimized. The specific operation is to place one shielding object inside another shielding object. Remember to have gaps between the objects. The gaps can be filled with supports, but they must be non-conductive materials.
In addition, there are many different ways to deal with magnets according to different magnet manufacturers. The key is to find suitable measures in specific applications.
