As per title, i would like to ask if there exists a program where i can create an arbitrary wire with an arbitrary current and get a visualization of electric and magnetic fields around it.

The emphasis is on simple, i am looking for something relatively easy to use to develop the intuition.

edit: my background is in molecular dynamics simulations of biological systems. If we can simulate a protein or a piece of DNA, if we can do hybrid QM/MM simulations of biocatalyzed chemical reactions, is it really so hard to simulate a coiled piece of wire ? :)


1 Answer 1


there are programs like this which are used to predict the behavior of antennas of any arbitrary size and shape. Ask about this on the amateur radio stack exchange for more information, but be warned: those programs are not simple, because the general problem is not simple either.
