ABSTRACT:
Methods and systems for magnetostatic modeling of a magnetic object is disclosed. A varying surface charge density is established at a surface of a magnetic object modeled by a magnetostatic model. Thereafter, a varying magnetic charge is generally distributed throughout a volume of the magnetic object to thereby accurately and efficiently model the magnetic object across a wide range of magnetic curves utilizing the magnetostatic model. The magnetic curves can be configured to generally comprise at least one non-linear magnetic curve and/or least one linear magnetic curve. Such magnetic curves may also comprise at least one magnetic curve in a magnetized direction and/or non-magnetized direction. Such magnetic curves are generally referred to as “BH curves”.
