can it ensure a Better Validity of the Point Dipole Approximation? S. ARAVAMUDHAN Department of Chemistry North Eastern Hill University PO NEHU Campus, Shillong 793022, Meghalaya When a homogeneously magnetized material is sub-divided into close-packed volume elements, then, each volume element gives rise to a dipole moment in presence of external field. Summing of the contribution of the induced fields due to these divisional moments calculated at a point within the sample, reproduces the already known values of demagnetization factors. Dividing a given total dipole moment into parts and distributing them to calculate the summed contribution of induced field at a distant point need not always result in the same value. The above alternate method of equivalent distribution of divided parts would be described with certain simple exercises as illustration.
