Abstract
This method of determining the horizontal intensity of the earth's magnetic field depends on well-known principles, which, however, do not seem to have been applied in exactly this fashion before. A magnet is suspended in a horizontal plane and allowed to vibrate under the joint influence of the earth's field and a known controlling field in the same direction and in either the same or opposite sense. The controlling field is that of two similar circular coils placed a distance apart equal to the radius (arrangement of Gaugain and Helmholtz).
