Magnetic stirrer

by Martin Malthe Borch

Nikolaj Møbius have developed a magnetic stirrer. We are now looking into publishing it in one of the new open source hardware journals.

The (electro) magnetic stirrer was developed as a proof of concept and it works quite well.

It uses 3 electromagnets to generate a rotating magnetic field thus having no moving parts instead of the classic magnetic stirrer design which uses an electric motor to rotate a permanent magnet.
