Lattice Arrangement (IMAGE) University of Notre Dame Caption This is a schematic image representing the new magnetic nano-structure and the formed magnetic charge ice. Nanoscale magnets are arranged in a two-dimensional lattice. Each nanomagnet produces a pair of magnetic charges, one positive (red ball on the north pole) and one negative (blue ball on the south pole). The magnetic flux lines (white) point from north-pole/positive-charges to south-pole/negative-charges.
