Abstract
The Square Kilometer Array (SKA) can deliver new data which will directly address currently unanswered issues concerning the origin and evolution of cosmic magnetism. An all-sky survey of Faraday rotation measures towards > 107 background sources will provide a dense grid for probing magnetism in the Milky Way, nearby galaxies, distant galaxies, clusters and in protogalaxies. Using these data, we can map out the evolution of magnetised structures from redshifts z > 3 to the present, can distinguish between different origins for seed magnetic fields in galaxies, and can develop a detailed model of the magnetic field geometry of the overall Universe.
