In both cases these measures use a linear current, whereas eddy currents are generally circulating around a cross-section, with a non-uniform amplitude depending on the spatial position. The magnitude of eddy currents is proportional to the material resistivity; …
WebWeld testing. Simple high frequency eddy current testers have been used for some time to detect toe cracks in ferrous welds. The method has the advantage of being able to detect cracks through paint layers. The disadvantages lie in the high noise levels caused by permeability changes in the weld and lift-off noise from rough cap surfaces. WebSep 12, 2024 · An eddy current is induced in a piece of metal close to the detector, causing a change in the induced current within the secondary coil. This can trigger some sort of signal, such as a shrill noise. Figure 13.6. 6: A soldier in Iraq uses a metal detector to search for explosives and weapons. (credit: U.S. Army)
