Eddy-current Material testing is one of many electromagnetic testing methods used in nondestructive. When the coil approaches a conductive material, currents opposed to the ones in the coil are induced in the material.
Variations in the electrical conductivity and magnetic permeability of the test object, and the presence of defects cause a change in eddy current and a corresponding change in phase and amplitude that can be detected by measuring the impedance changes in the coil, which is a telltale sign of the presence of defects.
