Engineering Physics Annotation << Back INSTRUMENT FOR MEASURING THE GRADIENT OF ABSOLUTE VALUES MAGNETIC FIELD F.F. MENDE The study of magnetic anomalies of the earth is of great practical importance for the exploration of mineral resources. However, such studies run into a lack of simple and highly sensitive instruments for such work. The paper describes a simple device for measuring the gradient of the absolute values of the magnetic field. Keywords: magnetic field, magnetic anomaly, crust, rock.
