e magnetic variation, or the variation ofthe compass. The angle DCE between the resultantdirection of the earths magnetic field and the horizontal is calledthe magnetic dip ; it is the angle of dip of a magnetised needle whichis free to rotate in the plane of the magnetic meridian. The resultant… … Fig. 730.—Magnetic declinationand dip. tan 6 VFT and I2 = H2 + V2. These quantities, the declination, dip, H, V and I are known astin magnetic elements at any point on the earths surface, and ifthe declination and any two of the other elements are known, thewhole of i hem may be calculated.
