FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used to study the excitation processes of EMF when rotating solutions of various substances, for example, acids (H2SO4, H3PO4 and others). In the method, the device includes a dielectric hollow disk rotating by the engine with a solution of the test substance. Further, the axis of rotation and the peripheral ring of the disk are made of a metal that does not interact chemically with this solution. And the peripheral part of the rotating disk with the test solution is placed in a permanent magnetic field of a permanent magnet, for example, neodymium, with steel magnetic cores. Induced EMF is removed by sliding contacts connected to the axis of rotation and the peripheral ring and connected to the load, for example, to a measuring voltmeter and a battery to charge it.
EFFECT: technical result consists in increasing the EMF.
