Abstract
Method of monitoring net magnetic bipolar orientation of magnetically permeable particles in a dry dielectric carrier layer around an electrical conductor by passing the layer covered conductor through a magnetic field to cause particle orientation to affect the magnetic flux strength in the field. Electromotive force or current induced in a sensing conductor placed in the field is affected by the flux strength of the field. Sensing any change in this induced property indicates a change in the net magnetic bipolar orientation.
