How can anyone define hardness, by means of its resistance & durability? The hardness is not just a term but a practical implementation of “Sustaining power that can never get worn-out, no matter how the thing is been put to the test.” While doing a hardness test, the mechanism of the hardness tester device, applies a fixed amount of load,…
Eddy current is one of the many non-destructive treatment methods that practices the principle of electromagnetism as a root to conduct the examinations. There are numerous other methods like Remote Field Testing, Flux Leakage, and Barkhausan noise who also uses the principle of electromagnetism. Electromagnetic induction is the process that generates an eddy current. When a conductor like the copper…
