PROJECT TITLE :

Transportation of Static Magnetic Fields by a Practically Realizable Magnetic Hose

ABSTRACT:

A practically realizable magnetic hose, created by wrapping a ferromagnetic cylinder with an alternating superconductor-ferromagnet (SC-FM) heterostructure, was developed and its capability to transfer the static magnetic fields, e.g., generated by a Nd-Fe-B magnet, is examined. A various dependence of the transfer potency on the diameter of the inner cylinder was found in the magnetic hose demonstrators and therefore the underlying cause was clarified by finite-part simulations. Transfer potency of over fiftypercent in terms of a moderate field was achieved in the best demonstrator of this study, even with a thin sheet having only moderate magnetism to embody the FM in the heterostructure. This work links a theoretically derived model with physical reality and additionally conceives solutions to make a magnetic circuit with minimum leakage or to make a magnetically shielded house, both of which are promising to be used in most electromagnetic devices.
