and environmental remediation. The fundamental principle underlying magnetic separation is the ability of magnetic fields to exert forces on magnetic particles, thereby inducing their movement and subsequent separation [1]. Magnetic separation relies on the interaction between magnetic fields and magnetic particles.

Conventional magnetic separation is to separate minerals according to their natural magnetism. In addition, in some cases, in order to improve the efficiency of separation, it is possible to change the magnetism of minerals or take some special methods to make the mineral separation more effective, such as magnetization roasting and magnetic separation, magnetic …

Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.

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.
