  Odd viscosity arises in systems with time reversal symmetry breaking, which
creates non-dissipative effects. One method to probe changes in viscosity is to
examine the dynamics of a single probe particle driven though a medium, a
technique known as active rheology. We show that active rheology in a system
with odd viscosity and no quenched disorder reveals a variety of novel effects,
including a speed up of the probe particle with increasing system density when
the background medium creates a velocity boost of the driven particle due to
the Magnus effect. In contrast, the probe particle velocity in the
dissipation-dominated limit monotonically decreases with increasing system
density. We also show that the odd viscosity imparts a Hall angle to the probe
particle, and that both the Hall angle and the velocity boost depend strongly
on the drive. These results should be general to other systems with odd
viscosity, including skyrmions in chiral magnets.
