In my universe technology is advanced enough to have non-jet and non-rocket booster technology.
For a disc shaped UFO all of the technology is crammed in the ship and there was no more room left for any landing mechanism and so the designers put really strong ultra rare magnets all around the sides.
Using Lenz's law would make the UFO fall slowly through a tube coming to a slower stop at the bottom.
I want to make this as accurate as possible so I would like to know any potential problems with this setup.
for those who don't know - Lenz's law states that when an emf is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced emf is such, that it produces an current that's magnetic field opposes the change which produces it.
