摘要: Tangled, primordial cosmic magnetic fields create small rotational velocity perturbations on the last scattering surface of microwave background radiation. For which redshift to a present value B{sub 0}=3 x 10{sup -9} G , these vector modes are shown generate polarization anisotropies order 0.1--4 {mu}K angular scales (500
