Query: Magnetism in the Brown Dwarf Regime   A suite of discoveries in the last two decades demonstrate that we are now at
a point where incorporating magnetic behavior is key for advancing our ability
to characterize substellar and planetary systems. The next decade heralds the
exciting maturation of the now-burgeoning field of brown dwarf magnetism, and
investing now in brown dwarf magnetism will provide a key platform for
exploring exoplanetary magnetism and habitability beyond the solar system. We
anticipate significant discoveries including: the nature of substellar and
planetary magnetic dynamos, the characterization of exo-aurora physics and
brown dwarf magnetospheric environments, and the role of satellites in
manifestations of substellar magnetic activity. These efforts will require
significant new observational capabilities at radio and near infrared
wavelengths, dedicated long-term monitoring programs, and committed support for
the theoretical modeling efforts underpinning the physical processes of the
magnetic phenomena
