The conditions are derived under which a symmetry operator quadratic in the momenta exists for a spin-zero structureless point charge interacting with an externally applied uniform magnetic field in the presence of a potential field. The conditions apply to the possible forms of the potential. The explicit form of the symmetry operator in general is constructed and some particular examples are examined.
