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.
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.
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.
