What is Magnetic Separation? Magnetic separation is a method of using magnets to remove magnetic and ferrous materials from mixtures. Essentially, when a magnetically susceptible material is placed in a magnetic field, magnets can exert magnetic forces on those materials, attracting them closer while non-susceptible materials remain unaffected.
