Electron Orbits (IMAGE) Georgia Institute of Technology Caption This graphic shows electrons that move along an equipotential, while those that follow closed equipotentials (as in a potential-energy valley) become localized (right). The arrows denote the magnetic field, while hills and valleys are small potential fluctuations.
