ON THE DEPTH OF BODIES PRODUCING LOCAL MAGNETIC ANOMALIES
( (Durham Colleges in the University of Durham) )
Some inequalities relating to magnetism are proved and their relevance to the interpretation of local anomalies in the earth's magnetic field is discussed. From observations of the resolved part, in any one direction, of the earth's magnetic field, these inequalities could be used to calculate (subject to certain hypotheses) a maximum possible value for the depth below the earth's surface of the top surface of the magnetized body producing the anomaly.
