Abstract
High aspect ratio filaments of magnetic material are randomly dispersed in a non-magnetic matrix such as paper or plastic for part of a critical component of a manufactured product to permit remote sensing of the manufactured product by the application of an external oscillating magnetic field and the detection of the resulting induced magnetization. The material may be incorporated into a wide variety of products that must be remotely sensed.
