The magnetic hose designed by the researchers consists of a ferromagnetic cylinder covered by a superconductor material, a surprisingly simple design given the complicated theoretical calculations and numerous lab tests it had to undergo. A 14-centimeter prototype was built, which transports the magnetic field from one extreme to the other with a efficiency of 400% in comparison to current methods used to transport these fields.
Even with the efficiency of the prototype, researchers theoretically demonstrated that the magnetic hose can be even more efficient if the ferromagnetic tube is covered with thin layers of alternating superconductor and ferromagnetic material.
The device designed by the researchers can be implemented at any scale, even at nanometre scale. Thus, a magnetic nanohose capable of individually controlling quantum systems could help to solve some of the current technological problems existing in quantum computing.
Magnetic Fields Guided by New Technology
Light, formed by magnetic and electric field waves, can be very effectively conducted through optical fibres. Nevertheless, "until now there was nothing similar with which to guide and transport static magnetic fields," explains Alvar Sanchez, ICREA Academia and leader of the research.
"To guide these fields in electronic circuits or in current transformers, ferromagnetic materials such as iron alloys are used, but their intensity quickly drops with the distance and their application is limited."
