Abstract

A SQUID magnetometer or a SQUID gradiometer can be used to measure the field or gradient distribution, respectively. We describe the magnetic dipole model of the eddy currents in a nondestructive evaluation. Such a theoretical calculation of the magnetic dipole fields produced by a deep flaw in metallic materials can be used in aerospace and transportation industries.
