FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering and can be used for creation of a homogeneous variable magnetic field. The device includes upper and lower Helmholtz coils and is provided with a laminated core, which has two cylindrical cavities with upper and lower end poles, in which Helmholtz coils are installed. A capacitor is connected to in-series connected Helmholtz coils, and power supply of the formed series circuit is performed by means of current of resonant frequency of the formed oscillating circuit.
EFFECT: technical result consists in reduction of a power supply unit capacity in order to obtain the specified level of magnetic field in working space of the device.
