Magnetic Field Cloak to Assist MRI Scanners and Medical Industry
Scientists from the Autonomous University of Barcelona have created a magnetic field cloak, or ‘wormhole,’ which could lead to better MRI scanning. “The wormhole allows a magnetic field to be transported across space but it is not the kind of cosmic tunnel popularised by science fiction. Rather, the magnetic field at one end of the wormhole appears at the other end as an … [Read more...]
