Simple simulator of a magnetic field in python. It's a toy, I don't plan to develop it further. But it works quite well.
Magnetic around a system of wires can be simulated and a-frame (WebGL) visualization constructed using a simple DSL:
Segment is a continuous wire. Wire is a collections of segments. Wires can be added and both segments and wires support simple geometric manipulations (translations and rotations). A Simulation needs one Wire and a collection of calculators.
