WebbEddy Current Testing is a versatile Non-Destructive Testing method, which capable to detect surface defects for conductive metal even without removal of coating of that material. An electromagnetic coil is utilized to produce a magnetic field. Eddy current brakes use the drag force created by eddy currents as a brake to slow or stop moving objects. Since there is no contact with a brake shoe or drum, there is no mechanical wear. However, an eddy current brake cannot provide a "holding" torque and so may be used in combination with mechanical brakes, for example, on overhead cranes. Another application is on some rolle…
