Stroboscopic Kerr microscopy observations of the dynamic magnetization process oil nanocrystalline Fe73Cu1Nb3Si16B7 tape wound cores with different induced longitudinal anisotropy are presented. talline tape wound cores with transverse ﬁeld-induced anisotropy, ” Acta Mater., vol. 54, pp. –,  F. Fiorillo, Measurement and Characterization of Magnetic Mate-. The invention relates to a method for producing a magnetic core and to a magnetic core produced thereafter. The method comprises the steps of: winding an amorphous band of a soft magnetic nanocrystallizable alloy having a first coefficient of thermal expansion onto a winding body of a material having a second coefficient of thermal expansion, wherein the second coefficient of thermal expansion is greater than the first coefficient of thermal expansion; a first heat treatment of the wound.
We report on the structural and magnetic characterization of two nanocrystalline Finemet-type magnetic cores. The nanocrystalline structure developed after annealing the amorphous precursor alloy at °C for 30 and 60 min of annealing time. Structural analysis carried out by means of X-ray diffraction providing useful information on the grain size mean and partial volume of the. The magnetization work W m was determined from the magnetization curve M vs. H as: (1) W m = ∫ 0 M S μ 0 M dH where H is the applied magnetic field and M is the magnetization. As it will be shown, in the longitudinal field annealed core this difference of W m is negative while in the case of transverse field annealing is positive. , Dynamic magnetization process of nanocrystalline tape wound cores with transverse field-induced anisotropy. Acta Mater. 54, – (). /t OpenUrl. Consider a rectangular current loop, with sides s 1 and s 2, located in a uniform magnetic field, pointing along the z axis. The magnetic dipole moment of the current loop makes an angle θ with the z axis (see Figure a). The magnetic forces on the left and right sides of the current loop have the same magnitude but point in opposite directions (see Figure b).
