The Magnetic Stirrer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution. The movement of this stir bar mixes the samples thoroughly with rapid movement and agitation. The Magnetic Stirrer is very effective and useful.
