The features of an advanced numerical solution capability for two-dimensional electromagnetic field problems governed by Laplace's Equation or, under certain conditions, by Poisson's Equation are outlined. Specifically, the relevant Boundary Integral Equation (BIE) formulation is presented, and a process for numerical solution is given based on assumed piecewise-quadratic variation of the boundary functions over boundary segments which, in turn, are assumed to be piecewise-quadratic curves between nodes. This numerical process based on quadratic assumptions is contrasted with the piecewise-constant or piecewise-linear assumptions which appear more commonly in the literature. A problem involving the forces on the windings in the “window” of a simple core-type transformer is solved for illustration
