actually it was Carl F. Gauss that invented the first absolute magnetometer in 1832 however there were other people that had devised versions of relative magnetometers earlier again. the difference between relative and absolute magnetometers is in the way they are calibrated the former being calibrated to a known external constant and the latter, being calibrated to its internal componants. Neither of these devices were originally devised for searching for oil. Charles Augustin de Coulomb had invented a version in the late 1700s, both he and Gauss had developed these devices as a means to acurately measure magnetic fields for their own reasearch
