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).
Additional design details are provided in the supplemental. documents. The total material cost of the magnetic stirrer and. that of the hot plate is US$29 and US$130, respectively. Stress tests ...

Jun 10, 2008 inside the stirrer base, using just a changing magnetic field. The stirrer had an adjustable speed over a very wide range. So it would seem to me that a wide range motor controller wired to a set of stator coils could do this. What I'm most curious about would be the shape of the core(s) these coils

The more we researched the topic, the more we found conflicting data on the coercivity of hard drive materials. One source said 1,250 Oe, another said 2,500 Oe. It seems that, in the race to make hard drives of greater storage capacities, hard drive manufacturers keep finding higher coercivity materials for the hard drive platters.
