a) Spatial distribution in the (r,z)-plane of the time-averaged Poynting flux given by Eqs. (15) and (16). b) Ohmic heating distribution, in arbitrary units. These results correspond to the transverse oscillation of a prominence thread with ρ_f/ρ_c = 200, ρ_ev = ρ_c, l/a = 0.2, a = 1, and L_thread = 0.2L. The magnetic Reynolds number is R_m = 10⁶.
