5. CONCLUDING REMARK
In this full paper preceding the presentation, it has been the effort to systematically document the salient results of the calculations which are taking the course from molecule to material. The ellipsoidal shapes are the ones which have the homogeneous magnetization for homogeneous susceptibility. Hence the case of inhomogeneity is yet to be discussed. More over when it is of importance to consider point by point summed contribution within the inner sphere, it must be obvious that even in the case of the favourable zero induced filed cases; the sum total of the discrete summation varies significantly from one point to other. If this summed value is significant compared to the bulk continuum contribution, then the assertion that the magnetization is homogeneous for spherical & ellipsoidal specimen would have to be reconsidered and ensure that it is only an average7 picture which is being refereed which includes averaging the discrete summing of point to point. This being so for diamagnetic specimen what would be the criteria set for magnetic materials where the internal fields are large? These points would be enumerated while presenting the material. The references cited here are mainly for the documentations made for the calculations made by this author. More references of much earlier efforts to handle internal field values at specific sites would also be referred and yet another version of this manuscript would become due after the presentation. The computer programs used by this author (written by the author himself in FORTRAN) are posted8 in the web pages. More over a simpler summation procedure could be evolved for the calculation of the shape dependent demagnetization factor. This is available as described in a manuscript posted in Ref.9
