Abstract

Although the emf from Chrome1-Alumel thermocouples is normally considered to be relatively insensitive to magnetic fields, a large error can occur due to the Ettingshausen-Nernst effect. This effect is largest below the Curie transition temperature where the Ettingshausen-Nernst coefficient, Q, for Alumel is large. A technique is described for directly measuring Q by employing an electromagnet in conjunction with an apparatus normally used for measuring thermal conductivity, electrical resistivity, and Seebeck coefficient.
