WebOct 1, 2024 · The physical composition of EMAT consists of three parts: permanent magnet, coil and specimen. The basic principle of its detection is: the bias magnetic field B S is generated by a permanent magnet, and a high-frequency current J S is passed into the coil to generate an alternating magnetic field. Due to electromagnetic induction, eddy … WebThe best eddy current instruments can detect cracks for complex inspections like tubing via multiple frequencies and dual options, and can pick up developing cracks as small as 0.1 mm or less in depth. When …
WebIn theory, magnetic particle inspection (MPI) is a relatively simple concept. It can be considered as a combination of two nondestructive testing methods: magnetic flux leakage testing and visual testing. Consider the case of a bar magnet. It has a magnetic field in and around the magnet. Any place that a magnetic line of force exits or enters ...
