WebBlog. Eddy current testing is a method of non-destructive testing, or NDT, that utilizes the process of electromagnetic induction for the evaluation and measurement of conductive materials without causing damage. Eddy … WebThe eddy currents are caused when the metal plate which is subjected to a magnetic field is take out rapidly. This causes current to flow within the metal plate and thus opposing the already existing magnetic field (Lenz's law).
