Halbach_two_point_oh: Optimize Uniform Fields with Permanent Magnet Arrays (V1.1.0)
Overview This Python program enables interactive exploration of the magnetic fields produced by rings of permanent magnets. It provides a Graphical User Interface (GUI) for investigating magnet geometries and field homogeneity. The physical background is based on: Halbach 2.0 — Creating Homogeneous Fields with Finite Size MagnetsIngo Rehberg and Peter BlümlerarXiv:2502.18262 Version History v1.0.1 This version includes a configuration inspired by: Sumit Tewari, Thomas O'Reilly, Andrew WebbImproving the Field Homogeneity of Fixed- and Variable-Diameter Discrete Halbach Magnet Arrays for MRI via Optimization of the Angular Magnetization DistributionJournal of Magnetic Resonance, Volume 324, 2021, 106923https://doi.org/10.1016/j.jmr.2021.106923 v1.1.0 Adds functionality to export STL files for 3D printing custom magnet holders.
How to get started: Unzip the file Halbach_two_point_oh.zip. Launch the interactive program by running halbach_two_point_oh.py. Using the program: To rotate the ring cluster, check one of the buttons labeled r_e, r_a, or r_r. Important: To stop the rotation, activate the stp checkbox. Preparing for 3D printing: Click the STL button and follow the provided instructions for exporting the model.
