I had the opposite. When we learned about magnets in high school, it was pretty much told assuming the atomic and crystalline scale of natural magnets to be a black box. Meanwhile, the instructions on electromagnets gave me enough to go off for me to extend that down to said crystalline and atomic level. So when I stepped to my teachers, claiming I had a theory and enthusiastically explaining that spinning electrons created an electric current, which in turn create magnetic fields at the atomic level, which can then line up with neighbouring ones to become a whole magnet, they responded “yeah, that is exactly how magnets work.”
