Abstract :
Using polarized flowing water, NMR detection at a high field region separated far away from the measured field was investigated to estimate ranges and conditions for a wide-range magnetometer. We obtained the Lorentzian-type NMR signal with the full-half-maximum width of 320 nT and the S/N ratio of 10.5, and measured the magnetic field from several mT down to a few μT with the same enhancement of signals by a separated NMR detector
