Slovak
scientists have invented a device that can create the illusion of invisibility by hiding objects from a static magnetic field,
researchers said on Tuesday.
Although it was a team of Barcelona-based scientists who came up with the
original idea, the three Slovaks from the Slovak Academy of Sciences were able to confirm it via experiments and created a magnetic invisible cloak.
The experiment was based on the fact that a specially designed cylindrical superconductor-ferromagnetic bi-layer can act as a cloak against a static
magnetic field.
"While the superconductor expels the magnetic field, the ferromagnetic material absorbs it. To make sure that the material used has the characteristics required, it needs to be cooled down to minus 195 degrees Celsius," Fedor Gomory, a member of the
research team, told a press conference.
The new device could be eventually used in advanced computer technology and where magnetic resonance machines are used in medicine. Research into the mysterious dark matter in the universe could also benefit from the new invention.
