Magnetic wormhole connecting two regions of space created for the first time

Universitat Autonoma De Barcelona

(Right) In terms of magnetism the wormhole is undetectable, which means that the magnetic field seems to disappear on the right only to reappear on the left in the form of a magnetic monopole. Scientists in the Department of Physics at the Universitat Autònoma de Barcelona have designed and created in the laboratory the first experimental wormhole that can connect two regions of space magnetically. This consists of a tunnel that transfers the magnetic field from one point to the other while keeping it undetectable - invisible - all the way.
