Aaron Purchase from the University of Alberta in Canada shares all the details to build an automated 3D fluxThe magnetic flux density, B, integrated over an area. The voltage induced in a coil is proportional to the flux... More density mappingThe process of measuring magnetic field intensity at many different points, in order to understand the structure of the field... More system. Aaron Purchase converted the Three-axisThe magnetic field is a three-dimensional vector quantity. A single Hall element only measures one component. A three-axis Hall instrument has... More Hall MagnetometerAn instrument to measure magnetic flux density (B) or magnetic field intensity (H). More THM1176 into a 3D mapper and shares the recipe. Aaron provides the hardware list as well as the software code Open Source, with no support guarantees from either the author or Metrolab. You can find the GIT repository here.
The interface to the probeThe actual sensor that is placed in the magnetic field. The NMR probe contains the NMR sample; the Hall probe... More is derived from the Python module shared by Cedric Hugon of Hyperfine Research. His Python module drives the Three-axisThe magnetic field is a three-dimensional vector quantity. A single Hall element only measures one component. A three-axis Hall instrument has... More Hall MagnetometerAn instrument to measure magnetic flux density (B) or magnetic field intensity (H). More THM1176. You can find the GIT repository here. But, again, this code is provided as Open Source, with no support guarantees from either the author or Metrolab.
A heartfelt thanks to both Aaron Purchase and Cedric Hugon for sharing. Of course, in the spirit of Open Source, we expect that any improvements you might make should also revert to the community!
