FIELD: electricity.
SUBSTANCE: device for investigating electric curl field consists of a ferromagnetic toroid rotating from a synchronous motor, connected to the frequency-adjustable polyphase alternator, magnetized in a circle, and a multiturn measuring coil installed without any contact near the mentioned rotating toroid and connected to a DC voltage meter through a DC amplifier. The turns of the measuring coil are located in planes collinear relative to the rotation axis of the ferromagnetic toroid magnetized in a circle.
EFFECT: simplified design.
