We revisit via a path-integral approach the magnetic top proposed rece
ntly by Barut, Boic, and Maric. We point out that the magnetic top has
the SU(2) symmetry and that it can be viewed as a free top seen from
a rotating frame. We present an alternative path-integral quantization
of the magnetic top on the basis of the symmetry, and show that the m
agnetic coupling does not participate in altering the spin quantum num
bers.
