Hysteresis measurement in LabView

This paper deals with the computer-aided automated magnetic scalar hysteresis measurement on ferromagnetic toroidal-shape material. The measurement has been developed in LabView environment using National Instrument Data Acquisition Cards. The measurement technique of symmetric minor loops and first-order reversal curves are presented. It is necessary to measure the magnetic hysteresis curves of ferromagnetic material to describe the material from magnetic point of view. The measured scalar hysteresis characteristics taking into account the nonlinearity of the material can be used in further simulations in numerical field computations.
