The method, based on well-known magnetoelastic effects, relies on mechanical stress-induced permeability modulation. It does not measure absolute values and hence results in suitable in situ measurements in situations where small position or vibration changes can change absolute values.engjournal articlehttp://dx.doi.org/10.1063/5.0050402https://aip.scitation.org/open access538.9Electrical steelsResidual-stressPermeabilityHysteresisModelFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
