README.mdMagnetic-Flux-Testing-Machine
A machine to collect data on how magnetic flux changes over distance. The end goal is to test how the air gap in an electric motor affects its performance. The machine involves spinning a disc of neodynium magnets next to a coil. The distance between the magnet disc and the coil is changed using a stepper motor, and the voltage across the coil is measured.

Questions
How big is the Coil board PCB?
It measures 35 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Coil board use?
9 parts, built around the KBU4A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Coil board KiCad files?
From the the-relentless-epee/Magnetic-Flux-Testing-Machine repository on GitHub, at the commit this page was made from: the board is Electronics/PCB files/coil board/coil board.kicad_pcb and its schematic Electronics/PCB Design Files/power board/power board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Coil board design in my own project?
Its repository states no licence, so its author keeps all rights: ask the-relentless-epee before reusing the design.
