Yes.

OH! I see now. Perpendicular-ness is not commutative in 3d. Gotcha, thank you!

Wait is that not true? Why wouldn’t H form a right angle with P and A?

AH would be perpendicular to n, and PH would be parallel to n, making them perpendicular to each other? Or am I misunderstanding the definition of a plane projection?

There weren’t any active communities I could find that my question would fit into, so I went with this one

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.

LocalSend is a very convenient cross-platform file-sharing app. It’s in the steam deck’s discovery store. Would recommend it over any usb drives or ssh.
