Fig.11. Three effects of inclusion driven by electric current^[49](a) electric free energy change when the inclusion is located at different positions (η=σ_p/σ_m, σ_p is conductivity of inclusion, σ_m is the conductivity of matrix, and η is conductivity ratio)(b) the force acting on inclusion (P—pushing, T—trapping, E—expelling)
