IN the macroscopic theory of electromagnetism there are several systems of equations that are compatible with SI units1,2. Among these are two important ones in current use which differ in their treatment of certain magnetic quantities. In one of these, introduced by Giorgi3, but now named after Kennelly, the field acting on a magnetic pole is considered to be the H-field, giving the couple T acting on a long thin magnet of moment j immersed in a linear magnetic medium as The degree of… Expand
