We have studied experimentally the magnetic field-inducedsuperconductor-insulator quantum phase transition in one-dimensional arrays ofsmall Josephson junctions. The zero bias resistance was found to display adrastic change upon application of a small magnetic field; this result wasanalyzed in context of the superfluid-insulator transition in one dimension. Ascaling analysis suggests a power law dependence of the correlation lengthinstead of an exponential one. The dynamical exponents $z$ were determined tobe close to 1, and the correlation length critical exponents were also found tobe about 0.3 and 0.6 in the two groups of measured samples.Comment: 4 pages, 4 figure
