Magnet suit in a giant copper tube? Slow-motion fun tunnels, can they work?
Isn't it a thing where the magnet induces a current in the pipe, which creates a magnetic field, which attracts the magnet slowing it's descent, but also decreasing the induced current and strength of the magnetic field until it finds a nice equilibrium point for itself?
Would it work with a pipe made out of another metal? Is there something that works even better than copper?
I am an idiot, it is just induced eddy currents.
Pull the neodymium magnets out from a dead HDD and rub them against the bottom of a heatsink, and you can feel the magnetic braking. And if you can get your hands on magnets + liquid nitrogen + a wafer of superconductor, you can really blow some fucking minds.
