Eddy Current Applications Slideshare. Eddy current (EC) testing is a no contact method for the inspection of metallic parts. Eddy currents are fields of alternating magnetic current that are created when an alternatin 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. Eddy currents (also called Foucault's currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction.Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. They can be induced within nearby stationary conductors by a time-varying magnetic field created by an.
Eddy current testing can be used for a wide range of applications. It is often applied for surface crack detection and material sorting. Material sorting is used to ensure that the proper materials are in use and to verify component materials or assembly features (such as the orientation or position of a subcomponent in an assembly). 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.
The advantages of eddy current testing are: Sensitivity to surface defects. Able to detect defects of 0.5mm in length under favourable conditions. Can detect through several layers. The ability to detect defects in multi-layer structures (up to about 14 layers), without interference from the planar interfaces. Can detect through surface coatings.
5 Applications of Eddy Current Brakes. Eddy current braking is a state of the art braking technology that has both economic and risk management advantages. This unique braking system takes the simple function of magnetic and non-magnetic forces and turns it into a high tech masterpiece. 5 Applications of Eddy Current Brakes.

Eddy-Current Brake Dynamometers (WB Series)are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy current braking SlideShare. Our Patented Eddy Current Magnetic Braking Technology. Basic Structure of Eddy Current Brakes. Eddy current testing 1. Eddy current testing can be used on all electrically conducting materials with a reasonably smooth surface. The test equipment consists of a generator (AC power supply), a test coil and recording equipment, e.g. a galvanometer or an oscilloscope Used for crack detection, material thickness measurement (corrosion detection), sorting materials, coating thickness.
