8 Flux Gate Magnetometer • Advantages Can make vector (directional) measurements Can record continuously • Disadvantages Sensitive to temperature Only measures field in direction of coils. With good insulation, 1nT accuracy can be achieved (typical accuracy 5 to 10 nT) Signal Proton Precession Magnetometer If external magnetic

Unformatted text preview: field changes, proton will ‘precess’ to align with new field • The precession frequency (Larmor frequency) depends on external field strength • Single proton nuclei exhibit an angular momentum, which yields a net-dipole moment • Moment of proton will tend to align with an external field...
