<jats:title>Abstract</jats:title><jats:p>The possibility of the commutational effect (CE) of thermo‐e.m.f. at different orientations of the magnetic field and temperature gradient is investigated in the frames of the variational method of calculation of transport coefficients. It is found that for some of the components of the magnetothermo‐e.m.f. tensor CE appears only in strong and intermediate fields. The importance of strict orientation of sample relative to external affects for the measurement of CE of magnetothermo‐e.m.f. is pointed out.</jats:p>
