FIELD: physics.
SUBSTANCE: core is composed of two self-contained elements, each in form of a metal plate with a vertical rod attached thereto. One of the plates is attached to a rectangular board with electric sockets. The primary coil is in form of a bobbin attached to the free end of the plate. The secondary coil is in form of a self-contained bobbin, the leads of which are provided with plugs, and is mounted on the vertical rod of the attached plate. A second plate with a vertical rod is a closing plate and is mounted with the rod inserted into the primary coil. The plate interacts through its free end with the rod of the attached plate. Leads of the winding wire of the mounted bobbin are connected to contact blades of electric sockets formed in the board, which are connected by connecting leads to either sockets of a direct current source or a switch or an alternating current source.
EFFECT: broader functional capabilities.
