Demonstration set on magnetic field of ring currents is designed for experimental demonstration of magnetic field created by electric current and force interaction between conductors when electric current flows through them. The laboratory provides the study of the dependence of the magnetic field induction on the current strength and the density of solenoid turns, the study of the magnetic field distribution of a flat coil and Helmholtz rings, demonstration of the interaction of coils with a current of the same and opposite directionality.
