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 - Sciencemadness Wiki

Aug 18, 2020 A magnetic stirrer is composed of two main components: the hot-plate stirrer device and the stir bar. The hot-plate stirrer is a piece of equipment which, as its name suggests, has the form of a hot plate and houses the magnet/electromagnet used for engaging the stir bar. Most are actual hot plates, being capable of both producing heat as well ...

All About Magnetization Direction

Our magnets are typically made in grades like N42 and N52. That “N” number relates to their maximum energy product, a measure of strength expressed in MegaGaussOersteds, or MGOe. While N52 magnets have a strength of 52 MGOe, a magnet made to work in any direction might only achieve 10-12 MGOe. That’s a lot weaker!
