Abstract
The present invention is directed to a non-contact detector for sensing a periodically varying magnetic field. The non-contact detector includes a probe having at least one magnetic sensor used to sense a magnetic environment generated by current running through a conductor. The detector includes means for periodically varying the magnetic environment and sensing means that is associated with each magnetic sensor that produces an electrical signal representative of the change in the magnetic environment. The detector also includes means for delivering a usable representation to a user in response to the sensing of the periodically varying magnetic environment.
