Как работает МАГНИТ | Самое понятное объяснение

Let's consider how a magnet works. The primary property of any magnet is the magnetic field it generates. The operating principle of electrical machines, transformers, electrical apparatus, and various electrical devices and instruments is based on the interaction of magnetic fields. Neodymium magnets are of particular interest, often used for non-magnetic applications, such as stopping meters, searching for rare artifacts, and so on. Their key feature is that neodymium magnets, given their mass and dimensions, are significantly stronger than magnets made of other materials. One of the most important characteristics of magnetic materials is magnetic permeability. It indicates how many times the material's magnetic induction is greater than that in a vacuum. Based on this property, materials are divided into five types: diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic. Neodymium is used as a magnetic material for the manufacture of permanent magnets, electrical machines, and other magnetic materials. Ferromagnets are used because they can amplify an external magnetic field by thousands and millions of times. Lesson 1. Magnetic Field.
