A material analysis system configured to determine whether a circuit is
defective includes 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; and 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.
