Halbach_two_point_oh: Optimize Uniform Fields with Permanent Magnet Arrays
Description
This Python program allows for an interactive exploration of the magnetic fields created by rings of permanent magnets. The background is described in:
Halbach 2.0 -- Creating homogeneous fields with finite size magnets, Ingo Rehberg and Peter Blümler(https://arxiv.org/abs/2502.18262).
The version 1.0.1 includes a configuration described by: Sumit Tewari, Thomas O'Reilly, Andrew Webb,
Improving the field homogeneity of fixed- and variable-diameter discrete Halbach magnet arrays for MRI via optimization of the angular magnetization distribution,

Technical info (English)
To start the program, unzip Halbach_two_point_oh.zip, and start the interactive program halbach_two_point_oh.py.
When rotating the ring cluster by checking of of the "r_e", "r_a" or "r_r"- buttons, make sure to stop the roation by checking the "stp"-checkbox.
