Abstract

Two nomograms or alignment charts are presented for the solution of the magnetic-dipole equations for magnetic intensity over a dipping dipole Δz = −m(d1/r13d2/r23) and Δh = −m(e1/r13e2/r23). The two charts are used in conjunction with each other and are as accurate as is needed for field work. One of these charts will be found useful also in other calculations involving d/r3.
