A portable Measuring Device suitable for Measuring the angle that makes the total electromagnetic field vector in the horizontal Plane tangent to the surface of the Earth At the measuring Point

摘要

Portable Measuring device which is used to determine the angle between the Vector of the total electromagnetic field of the earth with the horizontal Plane tangent to the surface of the Earth at a given Place, called angle of dip.It consists of detector coils (11a, 11b), First and second, which produce signals in response to the electromagnetic field of the Earth, being placed between the coils so that determine if a Straight Angle between both and such that one end of the first Coil is coupled to the Ction of the second Coil.
