Magnetovision scanner system investigation of magnetic field disturbance sources

Abstract

Paper presents the methodology and results of magnetovision scanner system investigation of magnetic field disturbance sources. Special measurement test stand, utilizing magnetovision scanner and tri-axial Helmholtz coils was designed and built. The measurements of the homogenous magnetic field distortions caused by various ferromagnetic objects were carried out. The magnetic permeability related distortion effect was investigated. The ability for passive detection of ferromagnetic objects and determine their location was demonstrated.
