The polarizing azimuth angle effect on sensitivity and the signal-to-noise ratio are theoretically analyzed in polarization pulsed magnetic field sensors. A novel scheme for improving the sensitivity of pulsed magnetic field sensors was proposed. The experimental results show the sensitivity is 1.8/T,1.9/T,2.9/T and 4.6/T respectively when the polarizing azimuth angle is 45°, 60°, 70°and 80°,so the sensitivity can potentially be considerably improved by setup suitable for the polarizing azimuth angle. The experimental results which agree well with the theoretical analysis prove the validity of this method.
