english: You won't be surprised to hear that if I take this circular magnet, in which the magnetic field is the same all around, the superconductor will be able to freely rotate around the axis of the magnet.
non_english: nebudete prekvapení, keď poviem, že ak vezmem tento kruhový magnet, v ktorom je magnetické pole všade rovnaké, supravodič bude schopný voľne rotovať po osi magnetu.
