I want to build the Magnetic Field Line Viewer but I wondered how you built the iron filings pick-up tool as I saw in your video at 1:33 https://www.youtube.com/watch?v=tW3wHLV-6xw&t=1s
I can’t find the name of it or another like it to reference.
I made a few iron filing magnetic pickups as see here at 4:40 mark: https://youtu.be/pWW9tyV3FTA .
Give me some time to find one and I will link it. If you want pics and material list on the ones I built let me know.
