Abstract
The magnetic field which induced by the thermo-electric current in metals was detected and measured using of a flux-gate magnetometer. It is shown that the application of a temperature gradient on a metal rod gives rise to a circulating current therein and induces a magnetic field in the vicinity of its surface. If a temperature gradient on a metal rod exists, the "hot"\ electrons flow from the heated region of a metal into a colder region and extrude "cold" electrons that form a current in opposite direction. Since the oppositely directed currents repel each other due to the interaction of magnetic fields, a convective loop of electron current formes inside a metalic sample. The magnetic field of this convection is directly proportional to the temperature gradient, the metal conductivity and inversely proportional to the temperature squared.
