1. A method of detecting anomalies in an ambient alternating current (AC) field, comprising the steps of:
- placing an AC field sensor in an ambient AC field;
generating a signal representative of the ambient AC field received by the AC field sensor; and
processing the signal to determine if the ambient AC field includes any anomalies.

19. A method of detecting anomalies in an ambient alternating current (AC) magnetic field generated by an AC power line, comprising the steps of:
-
supplying approximately stable AC current to an AC power line that causes the AC power line to generate an ambient AC magnetic field; placing an AC magnetic field sensor in the ambient AC magnetic field generated by the AC power line; generating a signal representative of the ambient AC magnetic field received by the AC magnetic field sensor; and processing the signal to determine if any anomalies are present in the ambient AC magnetic field.
