ABSTRACT:
An improved electronic magnetometer has a flux-concentrating core making grazing contact with a magnetically conductive element which is preferably part of a piezoelectric transducer. The core and transducer are mounted so as to make non-coherent, chattering contact when the transducer is caused to vibrate. A pickup coil attached to a signalling device enables a user to find a null in a field of magnetic flux with novel accuracy.
