There are several tools available for monitoring electrical metrics (voltage, current, resistance, frequency). I have recently acquired all that I need for these studies.
What tools are available for monitoring magnetic metrics (force, flux, reluctance, intensity, density)?
What I am really looking for is a tool that can give me a 3 dimensional representation of field lines. I am looking for a tool that (perhaps) uses the Hall effect to generate a 3D digital plot of potentially complex field interactions involving multiple magnets (possibly in motion). Are there off-the-shelf tools available within the budget of an average hobbyist? If not, could I build a 3-dimensional array of Hall effect sensors that could be arranged around my experiment to capture fields and field changes over time? I am good with writing software but new to circuit creation.
Add-on question: Are there other tools you would recommend for magnetic studies by a hobbyist?
