Abstract :
Tesla-to-ampere ratio giving the largest error in the γ´P-low-field-experiment has been determined using a modified noncontacting method. The total uncertainty of 0.164×10 -6 has been attained. The constant of a solenoid and the γ´P-value have been corrected for magnetic susceptibility of air. The result is γ´P=2.675 154 18×108 s-1 T-1 (Tesla BI-90) with the total uncertainty of 0.18×10-6
