Abstract

The existence of relatively intense and coherent magnetic fields in galaxies, clusters of galaxies and high redshift clouds is, at present, the subject of ' intense research. There are a variety of proposals aimed at explaining their existence and characteristics, but none is completely successful. We will investigate in greater detail previous research of A.K, during her PhD studies and of R.O. and his colleagues' on primordial magnetic field generation. The evaluation of these magnetic fields in the radiation and matter dominated eras will be studied. The effects of these magnetic fields on primordial nucleosynthesis, CMB(Cosmic Microwave, Background) and structure formation will be evaluated. (AU)
