What is the method of separation by magnetization?
What is the method of separation by magnetization? Magnetization Magnetization or magnetic separation is a process that takes advantage of the magnetic characteristics of some substances to separate different solids. Therefore, when small portions of these are scattered among other material, they can be separated thanks to magnetization. ...
