<p>A thermoelectric conversion member(1) formed of a thermoelectric conversion element has a split ring shaped transverse cross section. There are disposed electrodes(5,6) on ring ends of the thermoelectric conversion member(1) facing each other. A magnetic field generating unit(2) generates a magnetic field H in a direction perpendicular to the transverse cross-sectional plane of the thermoelectric converssion member(1). A heating unit(3) for heating one side of an annular wall of the thermoelectric conversion member(1) and a cooling unit(4) provided on the opposite side of the annular wall of the thermoelectric conversion member(1) produces a temperature gradient NABLA T in a direction radially of the thermoelectric conversion member(1). Electric field is induced in the direction perpendicular to both directions of the magnetic field H and the temperature gradient NABLA T, that is in the circumferential direction of the ring of the thermoelectric conversion member(1) under the Nernst effect, enabling an electric voltage to be taken out at the electrodes(5,6). <IMAGE></p> |
