Did anyone notice the description for the image at the top of the article? My understanding is that this description is nonsense, but I am an amateur and would love some clarification:
“A superconducting magnet is cooled by liquid nitrogen, producing a strong magnetic field that causes the magnet to levitate.”
Like superconductors don’t float because they’re a “strong magnet” they float because they reject all magnetic fields beyond the London depth and this somehow leads to levitation. Right??
