This study included the investigation of the effect of magnetic field of both north and south pole on the growth and viability of the local isolate of Aspergillus flavus, and its capability for the production of aflatoxin.The results showed that the north pole effect of the growth and viability of the tested isolate and it's capability for aflatoxin production. The colonies diameter were (50,60,70 )mm to the (north pole, south pole, north and south pole) treatments and the control was (60)mm. The numbers of spores to the same treatments were (12×107 ,50×107,31×107) spore/100 ml while the control was (30×107) spore/100ml.The dried weight of the same treatments were (0.11,0.36,0.25)gm while the control was (0.23)gm.The south pole show an efficiency in staining Aspergillus flavus sh1 comparing with the north pole. And so the North Pole was reduced the production of aflatoxin, while the South Pole increased the aflatoxin production.
