An electromagnetic-prospecting method in which the transmitter coil or loop is vertical and the receiver coil is in the plane of the transmitter coil. The null or minimum-coupling orientation is observed for the receiver coil. This orientation will be horizontal except near a conducting body. The angle between the plane of the coil and horizontal (dip angle) corresponds to the angle between the major axes of the ellipse of polarization and the horizontal.
