I didn't quite get the idea: > "This consists of a tunnel that transfers the magnetic field from one point to the other while keeping it undetectable – invisible – all the way". I guess that means generating a magnetic field on A, which can be detected on C, without being detected on an intermediate point B? > "This technology could, for example, increase patients' comfort by distancing them from the detectors when having MRI scans in hospital, or allow MRI images of different parts of the body to be obtained simultaneously." So that means placing the detectors away from the patient and making them receive the magnetic field through one of these "wormholes"?
