میدان مغناطیسی از یک رسانای نامحدود – کامسول

This introduction model creates a simple model of the magnetostatics problem with a wire of infinite length carrying current, which is commonly found in textbooks. Since there is an analytical solution to this problem, the model can be used to compare theory with numerical results from the simulation. The wire still has a finite radius in this example, giving different solutions for the regions inside and outside of the wire.
