Abstract
To the illegal stealing problem using strong magnets, the paper studied on the effect of neodymium magnet field on operation of single phase watt-hour meters. The experimental results show that the magnetic field of neodymium magnet increased braking torque of inductive watt-hour meters and caused the negative error, increased starting current， the instrument internal permanent magnet was magnetized, and anomalies of the permanent magnet degaussing can effectively detect electricity theft.
