The angle at the eye of the observer between a plane at right angles to the plumb-line, and a line drawn to a point on the visible horizon or line which seems to bound the ocean. When a magnet is suspended so as to swing freely round a horizontal axis at right angles to the magnetic meridian, it comes to rest at a certain definite inclination to the horizon; this angle (which is different at different places) is the Magnetic D.
