Magnetic illusion: transforming a magnetic object into another object by negative permeability

Materials Science 2018-03-22 v1 Superconductivity Applied Physics

Abstract

We theoretically predict and experimentally verify the illusion of transforming the magnetic signature of a 3D object into that of another arbitrary object. This is done by employing negative-permeability materials, which we demonstrate that can be emulated by tailored sets of currents. The experimental transformation of the magnetic response of a ferromagnet into that of its antagonistic material, a superconductor, is presented to confirm the theory. The emulation of negative-permeability materials by currents provides a new pathway for designing devices for controlling magnetic fields in unprecedented ways.
