End caps on hollow magnets

A compact parametric capped permanent magic ring structure producing a uniform magnetic biasing field, comprising:

• a cylindrical magnetic flux source having a cylindrical axis, a hollow central cavity, an inner diameter and a remanence perpendicular to said cylindrical axis;
• a first magnetic flux source, having a first cavity diameter, fully caps a first end of said cylindrical magnetic flux source;
• a second magnetic flux source, having a second cavity diameter, fully caps a second end of said cylindrical magnetic flux source;
• said inner diameter being equivalent to said first cavity diameter and said second cavity diameter;
• and
• said first magnetic flux source and said second magnetic flux source each generating a transverse magnetic field to assist in producing said uniform biasing magnetic field perpendicular to said cylindrical axis and confined within said hollow central cavity.
