High Gradient Magnetic Separation: An Industrial Application of Magnetism
A widespread commercial application of magnetism is the separation of mixed materials with different magnetic properties. Most magnetic separators use permanent magnets or electromagnets which remove ferromagnetic impurities such as bolts from non-magnetic products. Flour and cereal, among other common foodstuffs are subjected to cleaning by electromagnets. The grade of scrap iron is improved while loading it for transportation by lifting it magnetically which reduces the non-ferro-magnetic content.
