| Abstract: The work proposes an experimental demonstration method of the Lorentz force existence,useful in teaching the magnetism knowledge in high schools. The basic idea is that of getting a rotation movement of a electrolite placed into a circular cuve under the action of two fields: one radial electric and the other one magnetic,perpendicular on electrolite’s surface. Comparatively with the classic devices,the modules in the kit have the following advantages: they are easy to make with simple and cheap means; they use non-dangerous tensions, (max.12V), allowing the direct access of the pupils; they are longlife; they clearly stress the phenomenon, offering multiple possibilities of problematisation and leading discovery. |
