Nuclear Magnetic Resonance Spectrometer/magnetometer

This project involves building, a nuclear magnetic resonance magnetometer/spectrometer. With sample placed within the coils different N.M. relaxation signals may be detected from different materials. The primary field in this case is the Earth's. If the the equipment is placed away from power lines this field is sufficiently flat to characteurise samples.... Lots of good A-level physics here. :-)
