During automatic sorting of industrial parts, Eddy currents are used by observing the deformation of a magnetic field created by a coil when a part to be controlled is in close proximity.
Technology using Eddy currents can distinguish:
- Internal type defects within the material,
- Different mixtures of materials,
- Presence of heat treatment,
Thanks to localized probes, it can also detect surface defects on the part such as cracks or fissures.
