Magnetic Stirrer - an overview ScienceDirect Topics

Magnetic Stirrer - an overview ScienceDirect Topics

A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example. A magnetic stirring system generally includes a coupled heating system for heating the liquid (Figure 6.5).

Magnetic Stirrer - MRC- Lab

Magnetic Stirrer - MRC- Lab

A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (also called 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.

When you pull the arm down, the magnets in the arm and in the base repel each other. It takes about 55 lb of force to get them almost touching. Then, when the arm is released, the base magnets push the arm away, while the other set of magnets attract to the magnets in the arm. Several DX08B-N52 both attracting and repelling.
