Biomagnetic fields have very low amplitude compared to ambient noise fields and to the sensitivity of the detectors. This chapter graphically provides a summary of these fields. It indicates that it is possible to detect the MCG with induction coil magnetometers, albeit with a reasonably poor signal-to-noise ratio. However, even the most sensitive induction coil magnetometer built for biomagnetic purposes is not sensitive enough to detect the MEG for clinical use. Therefore, the Superconducting Quantum Interference Device (SQUID) is the only instrument that is sensitive enough for high-quality biomagnetic measurements.

Keywords:   biomagnetic measurements, biomagnetic fields, induction coil magnetometers, SQUID, signal-to-noise ratio
