Demagnetizing factors for cylinders
IEEE Transactions on Magnetics, 1991 Fluxmetric (ballistic) and magnetometric demagnetizing factors N/sub f/ and N/sub m/ for cylinders as functions of susceptibility chi and the ratio gamma of length to diameter have been evaluated. Using a one-dimensional model when gamma >or=10, N/sub f/ was calculated for -1 >

Harnessing Digital Microstructure for Simulation‐Guided Optimization of Permanent Magnets
Advanced Intelligent Discovery, EarlyView.An experimental‐to‐computational workflow is presented that transforms experimental 3D focused ion beam‐scanning electron microscopy data into a simulation‐ready digital microstructure for multiphase functional materials. Using heavy‐rare‐earth‐free Nd–Fe–B magnets as a model system, the approach quantifies grain connectivity across complex secondary ...

Demagnetization factors and field of hemispherical objects
Demagnetization factors play an important role in micromagnetics modeling but exact solutions only exist for a limited number of particle shapes. Here we use a Fourier space based approach coupled to the concept of magnetic charges to derive analytically

The anomalous demagnetization of pyrrhotite [PDF]
Geophysical Journal International, 1990 SUMMARY The anomalous behaviour of pyrrhotite-bearing rocks from the Pennine Orefield, northern England on alternating field demagnetization is studied with particular reference to rotational remanent magnetization (RRM). Using a heat treated sample, it is demonstrated that a two-axis tumbling demagnetizer is capable of producing a repeatable RRM ...
