Abstract
In order to control the direction of a magnetic field induced by a current sheet in a sheet conductor, relative to anomalies in a test sample, the current sheet is either rotated relative to the sheet conductor, by using either electrical or mechanical commutation of the current sheet, or the phases of plural independent current sheets in the sheet conductor are shifted relative to each other.
