We have investigated two models of the third elementary electromagnetic dipole, known as the toroidal dipole. Its magnetic realization is a circumferentially magnetized ring constructed of neodymium. The electric model of the dipole is a toroidal coil connected to a DC voltage. The electric and magnetic toroids produce only an inner magnetic field, inside the torus, and interact only on contact with the electric current density or when immersed in a time-dependent electric field. We studied the characteristics of a permanent-magnet toroid, and observed the influence of electric and magnetic fields on it. A static toroidal dipole moment of this …
