A very simple Helmholtz coil simulator I made for my physics exam in early 2013.

It is well-organized, but only very lightly commented. I made it before i learned about the object-oriented programming.

There are 4 versions:

• main.py
• main_grid.py
• main_grid_threaded.py
• main_grid_threaded_layer.py

A basic rule: the shorter the name, the earlier the version.

main_grid_threaded_layer.py should be bug-free and I have tested it on multiple computers running OS X, Linux and Windows. The earlier version are mostly to see the iteration of the software and help to understand the code.

I updated the code to Python 3, vpython and numpy. See main_numpy.py. It runs a lot faster, and should be slightly more understandable. Both vpython and numpy can be installed through pip: pip3 install vpython numpy.
