The nonlinear characteristics presented in Fig.<br />
2 have been used, and the curve has been<br />
approached by a simple piecewise linear<br />
approximation. This characteristic is the<br />
nonlinerar curve of a soft iron.<br />
The full paper will present and compare two<br />
potential formulations to solve nonlinear eddy<br />
current field problems by applying the Fixed-<br />
Point iterative technique. The formulations<br />
are the T,Φ – Φ – potential formulation and<br />
the A* – A – potential formulation of 2D<br />
time-stepping finite element analysis.<br />
