Abstract
Some aspects of the geometry of isomagnetic charts (using isomagnetic in a wide sense) are considered, particularly as regards their ray‐poles and singular points—foci and nodes. Special types of singular points are shown to include circular foci, rectangular nodes, and cusps. Some suggestions are made regarding the construction of isomagnetic charts.Keywords
