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 ? :)
