Abstract
The usual methods for formulating and solving the quantum mechanics of a
particle moving in a magnetic field respect neither locality nor any global
symmetries which happen to be present. For example, Landau's solution for a
particle moving in a uniform magnetic field in the plane involves choosing a
gauge in which neither translation nor rotation invariance are manifest. We
show that locality can be made manifest by passing to a redundant description
in which the particle moves on a
