How to understand the formation of magnetic force of suspension magnetic separator

The ferromagnetic substance used in the suspension magnetic separator is composed of molecules, which are composed of many atoms, and the atoms include the nucleus and electrons. Inside the atom, the electron is in a state of continuous rotation and rotates around the nucleus. Both of these electron movements are magnetic. However, in most materials, electrons move in different directions and are disordered, and the magnetic effects cancel each other out. Therefore, most substances do not appear magnetic under normal conditions.

The magnetic principle of the suspension magnetic separator: Ferromagnetic materials such as iron, cobalt, nickel, or ferrite are different from other materials. The electronic spins of these materials can be aligned in a small range to form a spontaneous This spontaneous magnetization region is also called magnetic domain. After ferromagnetic materials are magnetized, their magnetic domains can be neatly aligned and aligned in the same direction, which greatly enhances the magnetic properties, thereby forming a strong magnet iron.

The process of attracting iron by the strong magnet of the suspension magnetic separator is actually a process of magnetizing the iron block. After magnetization, the iron block and the strong magnet will form an attractive force, and the iron block can be very reliable The ground is ‘sticked’ with the strong magnet of the suspension magnetic separator, which means that the strong magnet of the suspension magnetic separator is magnetic.
