3D sketch of the magnetic wormhole, showing how the magnetic field lines (in red) of a small magnet at the right are transferred through it. (Right) From a magnetic point of view the wormhole is magnetically undetectable so that the field of the magnet seems to disappear at the right and reappear at the left in the form of a magnetic monopole.

First magnetic wormhole created in lab

Researchers in Spain have created the first–ever magnetic wormhole in a lab. The specially designed sphere is capable of transferring a magnetic field from one location to another ...
