The MiniDrive from GE's Inspection Technologies is an Eddy Current probe drive designed to make the inspection of fastener holes accurate and quick. Present State of Eddy Current Inspection. After reading this section you will be able to do the following: Explain what an Eddy Current is. As the electrical transformer is a static device, mechanical loss in transformer normally does not come into picture. Eddy currents are the consequence of time varying magnetic field. Zetec is the industry leader for cost-effective eddy current testing in complex applications. Abstract—An expression for the eddy current loss in solid rectangular cores is obtained using linear electromagnetic field analysis. Eddy Current testing uses the principals of electromagnetism as the basis for conducting inspections. Eddy currents (also called Foucault currents) are loops of electric current induced within conductors by a changing magnetic field in the conductor, due to Faraday's law of induction. Eddy Currents are closed loops of induced current circulating in planes perpendicular to the magnetic flux. The eddy current separation method usually sorts this non-ferrous scrap. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. Eddy current inspection is used in a variety of industries to find defects and make measurements. Faraday's Law implies that a changing magnetic flux produces an induced electric field even in empty space. Electrical eddy currents in the human body: MRI scans and medical implants. An eddy current brake, like a conventional friction brake, is a device used to slow or stop a moving object by dissipating its kinetic energy as heat. A simple explanation of how a vehicle or a machine can be brought to a halt with electromagnetic eddy current forces instead of friction.
