Magnetic viscosity and barkhausen noise in NdFeB-type permanent magnets
Journal of Magnetism and Magnetic Materials, 1997Abstract The Barkhausen noise and magnetic viscosity in sintered and melt-quenched needles of anisotropic NdFeB-type magnets are examined. In the sintered magnet, the time integral of the Barkhausen signal during magnetic viscosity is shown to correlate with the change in the bulk magnetisation as measured using a vibrating sample magnetometer.

Gear Quality Assessment Using Magnetic Barkhausen Noise Technique
2012The Magnetic Barkhausen Noise (MBN) technique is considered as a potential Non-Destructive Evaluation (NDE) method for assessing material properties in case-hardened gears. For gear manufacturing industries, the evaluation of material properties such as tempering induced changes in hardness level and the associated microstuctural changes, variations in

Using Magnetic Barkhausen Noise to Analyze Case Depth
AM&P Technical Articles, 2015Abstract Magnetic Barkhausen noise analysis is a nondestructive test method used since the 1980s to evaluate conditions in a variety of steel components. Primary applications include detection of thermal damage induced during grinding and evaluation of case depth in case-hardened parts.
