From the drawing it is evident, that a field with a very large gradient is apparent. 10 Gauss at 7 mm depth. The biologically relevant interaction can be assumed to about 10 Gauss which results an interaction of about 7 mm. 3 is the graph of the spatial field distribution for the two field components. 4 shows the same as a sprinkling picture.
Iron powder demonstrates the distribution of the magnetic field.
This study applies foils of 60x100 mm and strips of 20 mm width. The tests indicated, that the foil increases blood circulation in a very short time. A large number of patients indicate an increased temperature on the area of the foil, which could be proofed also by means of contact thermometer. The greater the disturbance of circulation of the area, the greater the possible temperature rise through the magnetic foil. The fact that the foil influences the circulation of an entire region is demonstrated in Fig. 5 and 6.
