1. A magnetic field generating assembly, configured to be associated with a table supporting a body, the assembly comprising:
a first plurality of elongate conductive elements arranged in a first plane, wherein each of the first plurality of elongate conductive element winds around a first central axis, extending perpendicular to the first plane, in a first spiral formation; and
a second plurality of elongate conductive elements arranged in a second plane, the second plane being substantially parallel to the first plane, wherein each of the second plurality of elongate conductive element winds around a second central axis, extending perpendicular to the second plane, in a second spiral formation; and
an isolated pattern of conductive elements;
wherein each of the first and second spiral formations is rectangular in shape;
wherein each of the first plurality of elongate conductive elements is interlaced with a corresponding one of the second plurality of elongate elements;
wherein each of the first plurality of elongate conductive elements is electrically connected to the corresponding one of the second plurality of elongate conductive elements; and
wherein each turn of the first spiral formation is located directly opposite a corresponding gap between successive turns of the second spiral formation in an unbending portion of the rectangular first and second spiral formations, wherein gaps are created at bended portions of the rectangular first and second spiral formations and wherein the isolated pattern of conductive elements fills the gaps between each of the first plurality of elongate conductive elements and each of the second plurality of elongate conductive elements,
wherein a width of each of the first plurality of elongate conductive elements is equal to or greater than a width of the corresponding gap.
