The steady state temperature distribution in a long current carrying cylindrical wire of a ferromagnetic superconductor at bath temperatures below the magnetic transition is obtained using some simplifying approximations. It is found that dissipation in this ferromagnetic resistive state would lead to the onset of a non‐equilibrium intermediate resistance state almost simultaneously in the entire cross‐section of the wire at a critical power level. The results indicate the dominant role of surface thermal transport in deciding the gross electrical behaviour of this non‐equilibrium reentrant superconductor under various thermal environments involving gaseous and liquid helium. The significance of these findings is discussed.
