• Resumen

  • In earlier work, Alvaro Sanchez at the Autonomous University of Barcelona, Spain, and his colleagues transferred a magnetic field across space with a superconducting hose. The team nested the hose inside a sphere of superconducting strips to deflect incoming fields. But that deflection would be detectable, so they put a magnetic sphere inside the strips to hide the superconductors--the fields cancelled each other out.
