Basic equations for gravity and magnetic fields

The basic formulae for gravity and magnetic fields were introduced in Chai)ter 1. According to these formulae the gravity field, g, satisfies the equaUons 

In particular, the c omnionIy measured vertical comi onent of the gravity field, g, can Ije foiind from the expression 

It is well known that the corresponding magnetic field H(r ), generated by the magnetic masses within a domain D, can be represented as follows (Zhdanov, 1988)  

Integral representations in forwcird modeling of gravity and magnetic fields 

Formulae (6.2) and (6.6) provide the basis for the solution of forward and inverse geopotential (gravity and magnetic) field problems.
