Abstract : Authors dealing with electromagnetism encounter difficulties of notation for quantities or dimensionless numbers related to this field, as the number of small and capital letters in the Greek and Roman alphabets is insufficient to cover the large variety of problems involved without avoiding successive uses of the same symbol in several different meanings. In an attempt to clarify this situation, the document proposes three systems of coordinates: cartesian, circular cylindrical, and spherical; a list of mathematical symbols in current use; a list of units of the rationalized Giorgi MKSA system; and a list of electromagnetic symbols particularly applicable to the study of the ionosphere.
