Many friends have heard of soft magnets and hard magnets. In daily production, they have also come into contact with these two types of magnets, but they have not had a deep understanding of the concepts and differences between them. In this article, Shenzhen Wan Xuan Magnetic Industry Co., Ltd. and everyone will analyze the difference between soft magnets and hard magnets.
1. The concept of soft magnets and hard magnets. Generally speaking, magnetic materials need to be magnetized and demagnetized. According to the difficulty of demagnetization, they are divided into soft magnetic materials and hard magnetic materials, and the magnets made of these two materials are further divided into soft magnets and hard magnets. Generally speaking, soft magnets have relatively small residual magnetism, while hard magnets have relatively large residual magnetism.
2. Application of soft magnets and hard magnets.
(1) Soft magnet mainly includes soft magnetic core and silicon steel plate. Soft magnets are widely used as channels for magnetic field lines, ie, as conductive materials. For example, transformers, sensor cores, magnetic shields, switching power supplies, displays, filters, special magnetic circuit yokes, etc.
(2) Hard magnets are mainly made of materials such as AlNiCo, SmCo, NdFeB and iron oxide. Mainly used in motors, electrical appliances, electronics, mechanical equipment, aerospace, smart home and other fields.
3. The use of soft magnets and hard magnets is different. If the magnet manufacturer turns off the power of the soft magnet, the magnetic force will disappear soon, but after the power of the hard magnet is turned off, part of the magnetism will remain, the iron core will become a magnetic field, and the magnetic field may change its direction. In this way, the transformer becomes a generator, and electrical appliances can cause damage. So, that's why power transformers use soft magnets instead of hard ones.
The above three points are about the difference between soft magnets and hard magnets. The analysis of Shenzhen Wanxuan Magnetic Industry Co., Ltd. is brought to you, hoping to help you understand!
