Magnetic incremental permeability testing
WebAug 2, 2024 · In conventional measurement schemes, the permeability of magnetic material is derived from the self-inductance of a cored inductor with a closed loop configuration and adequate thickness. In case of thin magnetic sheets, the toroidal core is made of many layers of the sheets cut into torus shapes. WebSep 15, 2024 · Magnetic Incremental Permeability (MIP) being highly stress dependent proves to be very effective to evaluate materials non-destructively. In this article, modelling technique based on Jiles-Atherton model has been proposed to simulate the signature MIP butterfly loop for the 12 Cr-Mo-V-W creep test samples.
