Wormholes are normally the stuff of science fiction, but new research carried out by a group of physicists in Spain has shown that it is possible to build the magnetic equivalent of a wormhole that is capable of transporting a magnetic field from one point in space to another. The team has built a spherical wormhole, made from ferromagnetic and superconducting components, that is magnetically cloaked. The researchers say that the work could prove particularly useful in magnetic resonance imaging.
