You cannot win, the energy to make superconducting magnets is much more than you would get out. | |
| Jan 18, 2018 at 10:10 | comment | added | Tomáš Zato | @annav That's what I meant. Harvesting energy stored in the arrangement of atoms that creates magnetic field - while increasing it's entropy. I wonder what would happen if you tried the same with superconductive magnet with persistent switch. | |
