Abstract:
1. A material analysis system configured to determine whether a circuit is functional or defective comprising: a magnetic field generator configured to generate a first magnetic field that is configured to induce at least one eddy current in a conductive portion of the circuit, wherein the eddy current induces a second magnetic field; a set of magnetic field sensors configured to detect the second magnetic field and generate a set of image information therefrom; a database that includes circuit information for the circuit; a computing device configured to receive the image information from the set of magnetic field sensors and retrieve the circuit information from the database, wherein the computing device is configured to compare the image information to the circuit information to determine whether the circuit is defective; an electrical stimulation device configured to electrically stimulate the circuit, wherein a current associated with the electrical stimulus is configured to generate a third magnetic field in the conductive portion of the circuit, wherein the set of magnetic field sensors is configured to detect the third magnetic field and generate a second set of image information therefrom, and the computing device is configured to receive the second set of image information from the set of magnetic field sensors and compare the second set of image information to the circuit information to determine whether the circuit is defective.
