Abstract

With reference to a device for pumping conducting fluids the behavior of this device subjected to a magnetic field produced by a real magnet was compared with that obtained utilizing an hypothesized map of the magnetic field. Through the use of the calculation code GFUN it has been seen that the magnet which most closely approximates the ideal shape is the saddle coil type. The features of the device were computed through a calculation code which schematizes the fluid with an electrical network that has lumped parameters: this was done taking into account the armature reaction and the magnetic field produced by the current of the leads which feed the electrodes.
