ABSTRACT:
The present invention is a well logging receiver coil system which includes a coil. The system also includes a variable capacitor connected across the coil to form a resonant circuit tuned to a predetermined frequency. The coil in the presence of an electromagnetic field has a current induced therein representative of the strength of the electromagnetic field. A pick-off circuit is connected to the coil in a predetermined manner and provides a signal representative of the strength of the magnetic component of the electromagnetic field substantially unaffected by the electrical field component of the electromagnetic field.
