The existing baryon spin and magnetic moment data are shown to be consistent with the chiral quark model prediction of a negatively polarized quark sea which has unpolarized antiquarks and a positive orbital motion. We also provide a simple calculation which explains why in our model the magnetic moment contribution by the quark sea must be proportional to that by the valence quarks.
