  The topological solitons, or ``skyrmions'', in a planar ferromagnet
experience a Magnus force proportional to the product of their velocity and the
surrounding magnetization. It has been suggested that the charged
quasiparticles near filling factor $\nu=1$ in the $GaAs$ quantum Hall effect
are skyrmions. If so we might expect this spin-induced Magnus force to act on
the quasiparticles in addition to the Lorentz force they experience because of
their charge. We show that this is not the case, and that the Magnus and
Lorentz forces are merely different descriptions of the same physical effect.
