**Physicists have succeeded in producing a wormhole of magnetic fields. In their experiment, the scientists let a magnetic field disappear from one place and reappear on another.**
*A wormhole for magnetic field lines.*
**Barcelona (Spain).** Physicists from the Autonomous University of Barcelona have produced a kind of magnetic wormhole. Wormholes is a kind of abbreviation of space and time, as they occur in numerous science fiction films and series. Here, however, it is not a question of the root-holes, with the help of which one can traverse the galaxy within a very short time, but a purely magnetic root-hole. In their experiment, the physicists have vanished the field lines of a magnet in one place and made it appear again in another place.
The magnetic field lines have traveled through a kind of invisible artificial tunnel: "From a magnetic angle of view, indeed, it behaves like a wormhole. As if the magnetic field had traveled through a different dimension, "explains Jordi Prat-Camps, one of the physicists involved in the experiment in Nature.
## Concentric spheres and a spiral cylinder produce the wormhole
For their experiment, the physicists have created a three-layered object consisting of a spiral cylinder inside and two concentric spheres, two spheres with the same center but different radii. The spiral cylinder consisted of a ferromagnetic material, which is also used to shield electrical devices. The whole experimental setup showed no magnetism.
The physicists describe the magnetic wormhole as follows: It consists of an outer spherical ferromagnetic meta surface, a spherical superconducting layer, and internally a ferromagnetic wrapped spiral cylinder.
If a magnetic source is now led to the one end of the experimental setup, it appears as an isolated magnetic monopoly. The missing lines appear some distance from the outermost sphere.
## Experiment already provides great achievements for science
Although we can still not travel to distant places in our galaxy with a wormhole, the experiment already provides great advances for physics and science in general. For example, in the future, the images of a magnetic resonance tomography (MRI) could be made much more pleasant in the future. The patients would no longer have to be pushed into a narrow tube, but the recordings could be made from a distance from the actual device." |
