    This paper presents LabView based method combined with a simple analog circuitry to characterize the ac magnetization profile of soft magnetic materials. First, soft magnetic materials prepared as ring cores are wound with equal number of turns for the primary and secondary windings. The primary winding is excited with sinusoidal supply of varying voltage amplitude. The secondary winding is interfaced with the LabView for data acquisition and calculation. Graphical plotting and viewing of the hysteresis loop exhibited by the soft magnetic materials under test can be achieved using National Instrument NI6009 data acquisition card and LabView software. This research discusses the methods of measurement for flux density, magnetic field intensity and core permeability at different points of the ac magnetization. The measured results are then compared with those given by the manufacturer datasheets. Good agreement has been achieved to validate the proposed LabView based method.
