Magnetostatic Fields


Magnetic Flux

By changing the size, shape and permeability of the rectangular shaped magnetic material one can see how the distribution of the magnetic flux lines are influenced by the material.

(1) 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.
(2) Click on the red triangles to change the value of the magnetic permeability of the material.
(3) Drag the red dots on the border of the rectangular material to change the shape and size of the material.
(4) The green line represents the plane in between the two current carrying conductors. The magnetic flux through this plane is calculated, the flux magnitude is represented by a green bar.

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.
