Character analysis technique is very simple and of basic importance in defining expressions of physical quantities where scalar and/or vector characters are to be determined. This article discusses briefly the application of recently established character analysis approach to few examples of electromagnetic equations existing in well-known textbooks. Furthermore it is shown that dotting a physical vector quantity by a non-physical operator such as a normal unit vector, does not change the character of the physical quantity. This dotting only gives the magnitude of the physical quantity in the direction of the unit vector. This component is still a physical vector quantity.
