«ادیکارنت» (Eddy Current)
"Eddy Current" is a non-destructive testing method used to check the quality of metal parts. This method is based on the phenomenon of electromagnetic induction. In this process, a probe (sensor) containing a coil generates an alternating electric current that creates an oscillating magnetic field. When this field approaches a conducting material, eddy currents are produced in that material, which are affected by changes in the properties of the material (such as cracks or changes in thickness).

It has several advantages, including high speed, no need for copplant materials, and the ability to identify surface and subsurface defects. However, it also has limitations; including the need for a healthy sample to compare and limit the depth of penetration [6†source] [8† [oai_citation:3, eddy current test (method of implementing Eddycarnet test, its advantages and disadvantages)] (https://namatek.com /%D8%AA%D8%B3%D8%AA-%D8%AC%D8%B1%DB%8C%D8%A7%D9%86-%DA%AF%D8%B1%D8%AF%D8% A7%D8%A8%DB%8C/) [oai_citation:4, inspection by Eddycarnet method - Mapva company] (https://mapvaco.com/%D8%AF%D9%BE%D8%A7%D8%B1 %D8%AA%D9%85%D8%A7%D9%86-%D9%86%D9%81%D8%AA-%D9%88-%DA%AF%D8%A7%D8%B2-%D9 %88-%D8%AA%D8%AC%D9%87%DB%8C%D8%B2%D8%A7%D8%AA-%D8%A2%D8%B2%D9%85%D8%A7%DB %8C%D8%B4%DA%AF%D8%A7%D9%87/%D8%A8%D8%A7%D8%B2%D8%B1%D8%B3%DB%8C-%D8%A8%D9 %87-%D8%B1%D9%88%D8%B4-%D8%A7%D8%AF%DB%8C-%DA%A9%D8%A7%D8%B1%D9%86%D8%AA/ )
Edicarnet is used in various industries such as aerospace, automotive, and metal industries to detect defects and check the quality of materials. For example, TMTECK brand TMD101 EdiCarnet device is used to measure electrical conductivity of materials and quality control【7†source】.
