This property of the earth's field is called "inclination." Although the geomagnetic field may be molded as if the earth were a permanent magnet, it is clear that this is not the case because thermal disordering temperatures of permanently magnetized materials are exceeded by burial greater ...
THE, precise constitution of the earth's magnetic field at any one time, and the causes of the constituent fields, are problems of fascinating interest, the solution of which appears destined' to reveal hitherto unknown properties of matter. A most intimate knowledge of the earth's magnetic ...

The magnetic intensity of the earth’s magnetic field makes an angle known as Angle of Dip (δ) with the horizontal axis. The intensity of earth’s magnetic field can be resolved into two components:Horizontal Component(H) Vertical Component(v) ...
The origin of the Earth''s magnetic field is one of the oldest problems in physics. The fact that the field is now known to have reversed its polarity many times in the past has given added interest to the problem. This paper discusses these issues and describes briefly the physical ...
