Description

Over the last several years, SQUID magnetometers have been utilized for detection of defects in metal structures by measuring the magnetic field produced by injected current or permanent magnetization [1,2,3]. Because the amplitude of the output signal from the SQUID magnetometer is independent of the frequency of the magnetic field to be measured, SQUIDs are suitable for dc or low frequency measurements as required for detection of subsurface flaws inside a conductor.
