Wow moment, indeed. Another reference
Great visuals. It is amazing how magnetism affects chemistry.
My retired collegue, Wayne H. Pearson, published a J. Chem. Educ. article (https://pubs.acs.org/doi/10.1021/ed300545y) on using an analytical balance and cheap, strong magnets to show paramagnetism and diamagnetism. He built a low cost, no waste lab which incorporates a lot of electron configuration practice which we still use every year. Before we started using this, every year on the midterm exam students got 40-50% on a multiple choice question about diamagnetism vs. paramagnetism. One we used Wayne's lab, the same question went to 88-95% correct. I have seen nothing like it for taking a misapplied concept and correcting it.
