5. Adjust two tabs of 6-pole magnets:
Superimpose the red and blue lines with the
green. Adjusting the angle affects the vertical
lines, and rotating both magnets affects the
horizontal lines.
6. Repeat adjustments 2~4, if necessary.
7. Since the 4-pole and 6-pole magnets interact,
the dot movement is complex ( Fig. 5-3).
