• We investigate the effects of magnetic fields on proto-neutron star winds by performing numerical simulations. We assume that the atmosphere of a proto-neutron star has a homogenous magnetic field (ranging from 10^<12>G to 5×10^<15>G) perpendicular to the radial direction and examine the dependence of the three key quantities (the dynamical time scale T_<dyn>, electron fraction Y_e, and entropy per baryon s) for the successful r-process on the magnetic field strength. Our results show that even with a magneter-class field strength, 〜10^<15>G, the features of the wind dynamics differ only little from those of non-magnetic winds and that the conditions for an effective r-process are not realized.
