A trio of physicists with the Autonomous University of Barcelona has built what they claim is the first artificial magnetic wormhole. In their paper published in the journal Scientific Reports, Jordi Prat-Camps, Carles Navau and Alvaro Sanchez describe how they built the device and why they believe it might prove useful in building a more user-friendly MRI machine.
People have grown familiar with the term wormhole as it applies to physics and science-fiction. It has been described as a portal in space-time, where an object, or perhaps a person, could be transported from one region of space to another, nearly instantaneously. And while the theory has stood the test of time, no one has ever been able to prove that they actually exist. In this new effort, the researchers built a much simpler version, one that applies only to a magnetic field. Their device essentially allows for a magnetic field to be conveyed from one point to another, while remaining magnetically invisible.

Going to RTFA now, but this sounds more like they use an interference pattern to have a magnetic peak somewhere inside the machine while minimizing field strength elsewhere.
