Recently, so many studies were carried out about interaction between magnetic field on the band of 0-100kHz and human biology. Many of them are adressed to the canser risk of children. In this paper, certain band fields to the ellipsoid human models were investigated. As ellipsoid human models, average man, average woman, average endomorphic (fat) man, 10-year-old-child, 5-year-old-child, and 1-year-old-child models were selected. Investigations were made for different situations and orientations. Field strenghts induced by the external 10 mG (1muT) field were estimated for different variations. In the situation of external field was in front of the body, the maximum value was faund. When the external field was positioned parallel to major axis, the minimum value was obtained. For example, for 10-year-old child model, at 10 kHz, when the magnetic field was parallel to lenght axis induced electrical field, (E-rms) was 1.923 mV/m. When the magnetic field was parallel to the intermediate axis of body, its value was 2.176 mV/m and it was parallel to the minor axis of body, optained value was 3.93 mV/m.
