By Edm. Halley. an assistant twice in the same hour with my observations of the dip, I will give some examples; Daily Variation. - Dip. Bifilar. " In order to ascertain if there is a monthly variation of the dip in the course of the year, I began, from April, , to observe the dip in its I made observations of the magnetical intensity and. Magnetic declination, or magnetic variation, is the angle on the horizontal plane between magnetic north (the direction the north end of a magnetized compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole).This angle varies depending on position on the Earth's surface and.

Norman's book gave the first lengthy treatment of magnetic dip and described a special instrument, the dipping needle, for measuring it. Norman, however, made no attempt to explain the cause of dip. In contrast to Norman's book, William Gilbert's De Magnete (), with a preface by London navigational authority Edward Wright, sought to explain.   Magnetic Variation in the United States: Being a Compilation of Observations Made in America From the Year to the Present Date; [Stone, Jacob Bennett] on *FREE* shipping on qualifying offers.

The discovery of dip excited for many years the hope that it would be able to be used for the determination of latitude, and thus avoid celestial observations and the accompanying calculations, or be useful in thick weather, just as it was hoped to use variation to determine longitude” (Waters, The Art of Navigation, pp. ).
