The knowledge about electromagnetical fields is the foundation of electrical engineering as a whole. The Maxwell equations are essential for the treatment of electromagnetical fields. Based on the field concept and the Maxwell equations, terms as gradient, divergence, curl, scalar potential, vector potential are introduced. The use of the differential operators div, grad and curl is discussed. Due to the broad usage of computers an emphasis on numerical algorithms and there usage for practical problems is placed.
