Generation of Hall voltage in bone.

Hall type voltage has been observed in bone and its two major components (collagen and apatite) in the region of moderately high electric and magnetic fields. The configuration of the sample placement and the experimental set up was the same as that adopted in standard Hall measurements. The resistivity of the sample has been related to the Hall Coefficients through the standard relationship and an estimate of Hall mobility was made. The Hall Coefficients were found to be of the order of 10(6) cm3 col-1 while the Hall mobility generally was in the region of less than 1 cm2/volt sec. A comparison with drift mobility suggests that the latter is at least two to three orders of magnitude less than the former. A possible mechanism underlying the said transport phenomena is discussed.
