Abstract
Apparatus for measuring the residual magnetization vector in cylindrical coordinates of a geological core sample. It comprises a carriage carrying a solenoid made to longitudinally vibrate for determining the longitudinal component of the vector and ferromagnetic transducers which determine the radial component and the phase of the radial component of the vector by rotating the core sample. The measurements are automatically integrated.
