摘要
A general method is developed to find the equilibrium magnetization and the eigenfrequencies (resonant modes) associated with a magnetic body of arbitrary shape based on the discrete dipole approximation. In this first of a series of papers the method is applied to the simple case of a line of dipoles with the magnetic field both parallel and perpendicular to the axis of the line.
