Magnetic stirrer consists of mainly three basic components: i)  Magnetic stir bar: It is commonly known as magnetic flea, stir rod or stir bar. This is a small cylindrical-shaped object made of materials like Teflon-coated stainless steel or PTFE (polytetrafluoroethylene). It is placed in the container or vessel containing the liquid to be mixed. ii) Stirring plate: It is the flat, electrically powered and the main component of magnetic stirrer. Commonly, it’s made up of material like ceramic or glass-ceramic. It consists of a heating element and a magnetic stir bar. iii) Magnetic field generator: This part is responsible for generating magnetic field and it is placed under stirring plate. This component causes liquids to spin and get mix well.
