SUMMARY:The Magnetic Universe Revealed Through Radio Polarimetry\, Ast
 ronomy Colloquium\, Bryan Gaensler\, The University of Sydney
DESCRIPTION:The evolution\, structure and origin of magnetic fields ar
 e stillopen problems in physics and astrophysics. When and how were th
 e first fields generated? Are present-day magnetic fields the result o
 f standard dynamo action\, or do they represent rapid or recent field 
 amplification through other processes? What role do magnetic fields pl
 ay in turbulence\, cosmic ray acceleration and galaxy formation? I wil
 l explain how radio polarization surveys have the potential to address
  these questions. Specifically\, I will present new Faraday rotation s
 tudies aimed at revealing the three-dimensional magnetic structure of 
 the Milky Way\, the Magellanic Clouds and distant galaxies. These stud
 ies pave the way to opening the full window to the magnetic Universe w
 ith the Square Kilometre Array and other future radio facilities.<br>
