What is the principle of a magnetic separator?

An electromagnetic concentrator is a device used to separate magnetic and non-magnetic materials. Its working principle is based on electromagnetics. When the current passes through a coil, it generates a magnetic field. When this magnetic field approaches the magnetic material, it will apply a force to the material, which will attract or repel the magnetic material, depending on their magnetic polarity. Through this principle, it is possible to mix magnetic and non-magnetic materials, apply a magnetic field to the material, and then separate the material attracted by the magnetic material from the non-magnetic material. Electromagnetic concentrators are widely used in industrial fields such as mining, recycling, and other processing of magnetic materials.
