The symbols "x" and "o" shown in red do denote impressed currents of opposite directions in conductors of
infinite length oriented perpendicular to the drawing plane. The positions of these current sources can be
changed by dragging with the mouse.
Attention: The magnetic flux lines are calculated using the finite element method. Because the computations are very time-consuming it is necessary to run the applet on a fast computer (>800MHz) in order to get good performance and high responsivness. We will improve the overall-performance of this applet in a future release by further optimizing the algorithms.
