Hmmmmm… My intuition tells me something like this could be possible with a vertical alternating magnetic field. If the paperclip formed a closed loop, eddy currents would produce an opposing magnetic field to hold it up. Sorta like in this video: https://youtu.be/5HnihTg1rso
Unfortunately I can’t find anything online showing this off, and I’m not really sure what could generate a field like that on the subway anyways.
