Magnetism Science with the Square Kilometre Array
  The Square Kilometre Array (SKA) will answer fundamental questions about the
origin, evolution, properties, and influence of magnetic fields throughout the
Universe. Magnetic fields can illuminate and influence phenomena as diverse as
star formation, galactic dynamics, fast radio bursts, active galactic nuclei,
large-scale structure, and Dark Matter annihilation. Preparations for the SKA
are swiftly continuing worldwide, and the community is making tremendous
observational progress in the field of cosmic magnetism using data from a
powerful international suite of SKA pathfinder and precursor telescopes. In
this contribution, we revisit community plans for magnetism research using the
SKA, in the light of these recent rapid developments. We focus in particular on
the impact that new radio telescope instrumentation is generating, thus
advancing our understanding of key SKA magnetism science areas, as well as the
new techniques that are required for processing and interpreting the data. We
discuss these recent developments in the context of the ultimate scientific
goals for the SKA era.
