Magnetic field manipulation devices

A magnetic field manipulation device comprising:

• an iron substrate comprising a surface and an array of segments comprising at least four segments;
• at least four electrically conductive non-concentric loops embedded in the surface of the iron substrate, wherein an individual electrically conductive non-concentric loop is embedded in an individual segment, and wherein individual segments of the array of segments are coupled together by a dielectric bonding agent such that the individual electrically conductive non-concentric loop of each segment is electrically isolated from electrically conductive non-concentric loops of adjacent segments in the array of segments;
• and
• the at least four electrically conductive non-concentric loops are arranged in the surface of the iron substrate such that the magnetic field manipulation device converges magnetic flux lines of a magnetic field generated by a magnetic field source positioned proximate the magnetic field manipulation device.
