Abstract : An azimuthally circumscribed section of a hollow hemispherical magnetic flux source (i.e., a quarter-spherical or one eighth-spherical structure) has a superconducting planar sheet abutting one flat face of the section and, at least, a second planar sheet of selected material (e.g., paramagnetic or diamagnetic) abutting another flat face of the section and perpendicular to the first sheet. The magnetic mirror image of the magnetic section in the diamagnetic (superconductor) plane and the virtual (anti-mirror and/or mirror) image(s) in the other perpendicular plane(s) makes the central cavity appear (magnetically) exactly as if a complete magic sphere were its source. The central or working cavity is readily accessible through a hole in the first or second planar sheet.
