Even though the interstellar medium (ISM) of star-forming galaxies has
been known to have a multiphase structure (broadly hot, warm, and cold
phases) since the 1970s, how magnetic fields differ between the ISM
phases is still unknown. Using a combination of theory, simulations,
and
observations, this talk explores how the multiphase nature of the ISM
shapes magnetic fields. In particular, using Zeeman magnetic field
measurements and pulsar observations, the relationship between the
turbulent kinetic and magnetic energy densities will be established.
The
findings from these studies will enhance our understanding of the role
of magnetic fields in star formation and galaxy evolution, and also
prepare us to harness the upcoming wealth of radio polarisation data
from the SKA.
