The permeability (magnetic conductivity) of a material is essential for many applications. For example, the fatigue state of nickel-based steels can be monitored in high-temperature applications, or the permeability of components for an electric motor can be checked. In today's video, we look at the principle of measuring smallest permeabilities (µr 1.0000 – 2.0000) in theory and practice. • Do you have recommendations for further videos? Write your suggestions in the comments! • The eddy current method plays an essential role in various industries such as aviation or automotive. You can find more information about the application of eddy current testing under the following links: • Blog: High-temperature corrosion on turbine blades (Sulfidation) (foerstergroup.com) • Website: https://www.foerstergroup.de/de/deu/ • LinkedIn: / insti. . • My name is Manfred Schmitz and I have been working in the field of non-destructive testing since 2014. NDT is an extremely exciting field for me because of the wide range of applications. The scope from testing people by CT (computed tomography) or medical ultrasound to materials testing with eddy current is incredible. • Time stamps: • 0:00 Intro • 0:11 What is the magnetic permeability. • 1:32 Measurement principle to measure the permeability µr 1.0 – 2.0 • 2:06 Calibrate the measurement system • 2:45 Measure the permeability • 3:06 Test for the correct permeability • 3:44 Outro
