Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Locator of the weak magnetic fields sources Grigorashvili Yu.E., Karpov R.G., Bukhlin A.V. In this article authors consider basic operating principles of a device intended for locating weak dipolar magnetic field sources. The problems associated with constructions of magneto-sensitive antenna of such locator as well as problems of computer processing and visual representation of dipolar source’s spatial location have been investigated.
