ABSTRACT
The electrical and magnetic effects in materials are closely related because both are dependent on the electrons. Many of these properties are structure insensitive, so that they are not useful for the purposes of nondestructive evaluation of structure of materials. We must, therefore, identify the magnetic and electrical properties that may be of interest for our purposes. We first ask what happens when a material is subjected to an electric field, and then, what happens when the same material is subjected to a magnetic field. From these responses, it is possible to identify measurements that can be used for nondestructive evaluation.
