VIBRATING SEARCH COIL AND MAGNETIC FIELD DISTRIBUTION MEASURING APPARATUS USING VIBRATING SEARCH COIL

摘要

A detection coil is provided that provides high spatial resolution by minimizing the effect on the detection coil by the leakage magnetic field generated in the vibrator. The vibrating detection coil includes a vibrator that generates magnetic deformation at a frequency 2f when an alternating magnetic field having a frequency f is applied, and a detection coil connected to the vibrator.
