A solid state mechanism for cooling high-current cables is proposed based on the Ettingshausen effect, i.e. the transverse thermoelectric cooling generated in magnetic fields. The intense current running in the cable generates a strong magnetic field around it, that can be exploited by a small current running in a coating layer made out of a strong "thermomagnetic" material to induce a temperature difference between the cable core and the environment. Both analytical calculations and realistic…

Effects of temperature dependence of electrical and thermal conductivities on the Joule heating of a one dimensional conductor

We examine the effects of temperature dependence of the electrical and thermal conductivities on Joule heating of a one-dimensional conductor by solving the coupled non-linear steady state electrical

Infinite-stage Nernst-Ettingshausen Cryocooler for Practical Applications

Recent developments in Nernst-Ettingshausen (NE) physical phenomena combined with advances in the performance of rare-earth permanent magnets make thermomagnetic (TM) cryocoolers well suited for

Polycrystalline MnBi as a transverse thermoelectric material

To assess the potential of polycrystalline MnBi as a transverse thermoelectric material, we have experimentally investigated its anomalous Nernst effect (ANE) by means of the heat flux method. We
