If hair follicles are steered by bio magnetic fields creating whorls and grain patterns, I wonder if fingerprints are simply a byproduct of the magnetic field of electrical impulses running through nerve bundles in the fingers.
These hair follicle patterns would be laid down in utero (Wunderlich, RC, Heerema, NA: Hair crown patterns of human newborns. Studies on parietal hair whorl locations and their directions. Clin Pediatr 1975, 14: 1045–1049, ISI ChemPort ) and since newborns come with both hair whorls and fingerprints the patterns are laid down early.
Oddly the only areas where patterned skin ridges exist are in the palms of hands and soles of feet where nerve bundles are concentrated.
If this hypothesis were true you would see variations in fingerprints based on nerve disorders and that evidence exists;

KEYWORDS Finger Print Pattern. Total Finger Ridge Count. Absolute Finger Ridge Count. Leprosy
ABSTRACT Finger print patterns of 150 leprosy patients (100 paucibacillary and 50 multibacillary leprosy) were compared with 100 controls matched accordingly. The finger print pattern such as whorls, loops, arches, total finger ridge count (TFRC) and absolute finger ridge count (AFRC) were calculated. These dermatoglyphic parameters were compared to that of the controls. It was observed that the finger print pattern showed increase in the whorls and decrease in the loops in paucibacillary leprosy patients and increase in the loops and decrease in whorls in multibacillary leprosy patients (p<0.001) which is highly significant when compared to that of the control. The difference in the mean TFRC and AFRC in paucibacillary and multibacillary was also found to be highly significant (p<0.001) when it was compared to the control.
Are we simply looking at magnetic field steering in biology? Interesting question.
