Antimagnet [Microwave Surfing]

Maxwell´s equations can be harnessed to design an antimagnet, a cloak that would, on one hand, conceal the static magnetic field produced by an object inside and, on the other, would not perturb an external static magnetic field. The new antimagnet cloak has an inner layer fabricated from a high-temperature superconducting tape, which, on its own, repels the magnetic field. The outer ferromagnetic layer is made from a thick FeNiCr alloy sheet and, on its own, it draws in the magnetic field lines.
