Among the various nondestructive testing methods, the electric potential method requires relatively simple device and measurement. However, because of the high electrical contact resistance, sometimes it is difficult to measure the correct local electric potentials by direct contact. In order to overcome this difficulty, method is proposed which involves substituting the local magnetic field for electric potential measurements. The comparison with the conventional electric potential method demonstrates the usefulness this method, especially for materials with low resistivity.
