Abstract
The general theory of electric current multipoles appearing due to the motion of magnetic dipoles and the change in these values or orientations are suggested. Static multipoles, including an anapole, are studied in detail. Electric current multipoles (ECM) occur due to the motion of conductors car-rying current and due to the variation of the current strength in conductors. While possessing a number of typical multipole properties, they have some interesting dis-tinctions. Typically, electric charge multipoles occur due to a particular spatial
