Abstract:
Magnetic fields are an ubiquitous presence in our Universe but a 
comprehensive theory describing their generation and evolution is still 
missing. An intriguing possibility is that these fields are generated in 
the pre-recombination Universe and then evolve passively until the epoch 
of structure formation. A clean way to prove the presence of primordial 
magnetic fields (PMF) is to look at Cosmic Microwave Background (CMB) 
anisotropies induced by these fields. In this talk, I will review the 
current and future bounds on PMFs as coming from the observation of the 
CMB. Finally I will discuss how magnetic fields evolve in the 
post-recombination regime and their impact on structure formation
