Magnetic liquid, also known as magnetic flow, iron magnetic fluid or magnetic liquid, is a stable collagen solution mixed with strong magnetic particles, base liquids, and interface active agents. When an external effect is added, the magnetism is displayed. You can first wrap the FE3O4 magnetic particles on a layer of surfactant, and then disperse it in the base solution
