Beschreibung
Zusammenfassung:A system for measuring magnetic fields outside a ferromagnetic container from inside the same container is described. The invention uses magneti circuits to direct the flow of magnetic flux to a magnetic field detector. By using magnetic fields for detection, this invention is able to measure the properties of magnetic materials outside the ferromagnetic container, such as a geologic formation, electric or magnetic parameters, or log well and drill holes that have been cased.
