Abstract

A difference in the potentials in a nonuniform magnetic field is shown to occur across electrodes that are placed into a ferromagnetic suspension, which is used in magnetic-powder nondestructive testing (NDT). This phenomenon may be used for the detection of flaws in ferromagnetic products.
