PPT-Eddy Current Inspection Basic Principles

Eddy current inspection is one of several NDT methods that use the principal of electromagnetism as the basis for conducting examinations Eddy currents are created through a process called electromagnetic induction When alternating current is applied to the conductor such as copper wire a magnetic field develops in and around the conductor This magnetic field expands as the alternating current rises to maximum and collapses as the current is reduced to zero If another electrical conductor is brought into the close proximity to this changing magnetic field current will be induced in this second conductor Eddy currents are induced electrical currents that flow in a circular path They get their name from eddies that are formed when a liquid or gas flows in a circular path around obstacles when conditions are right. It is used for measuring targets made of electrically conductive materials which may be either ferromagnetic or nonferromagnetic A highfrequency alternating current flows through a coil cast in the sensor housing The electromagnetic coil field induc 1. .
