Calibration of a permeameter for measuring soft magnetic materials using long cylindrical samples characterized by demagnetizing-corrected solenoid method.

A technique is developed to calibrate the performance of a permeameter for measuring soft magnetic materials, having a C-shaped magnetic potential H -coil near the sample surface and a B -coil surrounding the sample, by using cylindrical standard samples. The true M ( H ) curve for the standard samples of large length-to-diameter ratios is obtained by the demagnetizing-corrected solenoid method recently developed. [ABSTRACT FROM AUTHOR]
