Heat Conduction and Magnetic Field Induction in the Presence of Cold-and Hot-Electron Maxwellian Distributions

A Maxwellian velocity distribution with cold and hot electrons causes the electron heat conductivity associated with the cold component (∇Tc) to decrease and even change sign in a weak magnetic field or parallel to a strong magnetic field. The same occurs transverse to a strong magnetic field and to ∇Tc but not parallel to ∇Tc. Nonetheless, the total heat flow retains its proper sign as a result of new contributions from ∇nc and possibly ∇Tₕ. Various transport properties and the self-generated magnetic field are also analyzed.
