We present a target-field approach to analytically design magnetic fields using permanent magnets. We assume that their magnetization is bound to a two-dimensional surface and is composed of a complete basis of surface modes. By posing the Poisson’s equation relating the magnetic scalar potential to the magnetization using Green’s functions, we derive simple integrals that determine the magnetic field generated by each mode.

Local LitLOCAL LIT: ‘Happy Old Year’Old year, you were all right, if a bit strange,like a homely doll that comforts uswhile lying in bed trying not to hearour parents arguing. You were the catsnarled with burdock and stick-thin who shows upat our door, who, brushed and fed, loses someof the fear in his eyes. And you werethe new song that sounds odd but which we beginto love after we’ve heard it a few times.

Local LitLOCAL LIT: ‘The Christmas Pageant’In this celebration of a birth, still so many birds of death flit through the shadowy bushes of the hymns. The pageant brings a welcome lightness with its tender comedy of confident older kids and uncertain younger ones. Glittery cardboard angels’ wings and cotton-ball sheeps’ wigs are as real as they need to be, and the three kings’ recitation, out-of-sync unison, makes everyone fond.
