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: Ne bo vas presenetilo, da ko bomo vzeli ta krožni magnet, po katerem je magnetno polje povsod enako, se bo superprevodnik lahko prosto vrtel okrog osi magneta.
