‘Antimagnet’ renders magnets invisible

Published in Nature, 22 Mar 2012

Physicists have already unveiled invisibility cloaks that can hide objects from light, sound, seismic and even water waves. Now researchers report a cloak that can hide objects from static magnetic fields. This ‘antimagnet’ could have medical applications, but might also subvert airport security.

Writing in Science, a team of theorists led by Alvaro Sanchez at the Autonomous University of Barcelona in Spain, together with experimentalists at the Slovak Academy of Sciences in Bratislava, describe a magnetic cloak made with inexpensive, readily available materials. […]
