Magneticseparationis a well-established technique, having been used in many industrial processes since the mid-1800s [1]. It essentially involves the use of amagneticfieldgradientto isolatemagneticparticles from nonmagnetic fluids or materials. The firstmagneticseparators used large electromagnets to extract iron from ferrous ores, and
