We present measurements of the transverse magnetostriction from a likewise oriented magnetic flux density in a conventional grain oriented silicon-iron sheet. A data processing scheme to extract nonlinearity and frequency dependency parameters from such measurements is shown. A good fit is obtained with six reals representing flux density excitation, four for material nonlinearity and three for time rate dependency. Model use in a finite element surrounding is indicated.
