The symmetries of rectification current and photovoltaic current with respect to applied magnetic field are examined. Theory and experiment are found to be in good agreement throughout a broad range of frequency and ac power, ranging from adiabatic to nonadiabatic regimes.4 pages, 3 figures; related articles at http://marcuslab.harvard.eduMesoscale and Nanoscale Physicstext
