Abstract: Transport processes in the fully ionized plasma with kappa-distribution and in strong magnetic field are studied. By analyzing the current density and the heat flux in the κ-distributed plasma, we derive the corresponding transport coefficients, including the electric conductivity, the thermal conductivity and thermoelectric coefficient. Besides, we derive the coefficients of Hall, Nernst and Leduc–Righi effects in the κ-distributed plasma. It is shown that these new transport coefficients depend strongly on the κ-parameter and only in the limit κ→∞, they recover the traditional forms in the plasma based on Maxwellian distribution. We also numerically analyze the role of the κ-parameter in the κ-dependent transport coefficients.
