Magnetic properties and uses of ferromagnetic materials

Iron, nickel, cobalt and their alloys can greatly enhance the magnetic field, so they are widely used in electrical technology. Under the action of the external magnetic field, the molecular current in the ferromagnetic material can be arranged from a disorganized and destructive distribution state to the direction of its magnetic field and the external magnetic field, so an additional magnetic field that is far stronger than the external magnetic field is formed. Arranging molecular currents causes the magnetic field within a ferromagnetic material to increase dramatically, an effect called magnetization. Certain magnetic properties of ferromagnetic materials are revealed from the process of magnetization.

Permanent magnet traction technology--China's breakthrough in the field of magnetic materials

Permanent magnets, which can maintain continuous magnetism for a long time, such as the application of more artificial permanent magnets (mainly NdFeB), which are made of some metals and new materials after systematic processing, they can have long-term magnetism, around the magnets. In the presence of a magnetic field, the iron will be magnetized, and the magnetized iron block and the magnet can have the effect of attracting opposites, and the iron block is firmly adhered to the magnet.
