Earth’s Field NMR involves very sensitive magnetic fields that must be held static for experiments to succeed. As part of a revamping of the introductory physics curriculum, UBC Physics plans to outfit a lab with a number of small EFNMR scanners that can be operated by students. Preliminary experiments conducted in the planned space have shown that there is significant DC field interference, most likely produced by the nearby elevators. Due to the low frequency of the interference, and the dynamics of elevator use throughout the day, an active field stabilization system is required if the EFNMR labs are to proceed as scheduled. The effort to realize a field stabilization system as outlined above is being funded by UBC Physics, with cooperation from the Engineering Physics Project Lab. Success will mean not only that the new EFNMR labs can proceed in the coming 2013 school term, but will also represent a unique solution to the problem of shielding a large volume of space from DC interference. One can find applications for such results anywhere requiring the simultaneous operation of many NMR scanners in close quarters. The details of the designed system may, therefore, be of enough merit to warrant a scientific publication detailing the process so that others may benefit from the work.
