Beschreibung
Zusammenfassung:	The invention relates to a method for studying the properties of a spinning magnetic field of an electric machine. According to the invention, the method consists in that a rotor of an electric machine is assimilated to a vessel (1) made of non-magnetic and non-conductive material, partially filled with a ferromagnetic colloidal solution (2) or with a ferromagnetic powder over which a powder (3) playing an indicator role resulting from crushing the gold leaves is spread, said powder (3) being driven into motion by the magnetic-active particles, so that the paths of motion of said particles may be identified by carrying out motion images of the gold powder (3) by means of a digital camera.
