clever idea for proton mag

[William Beaty]

Here's someone with a clever idea for a proton mag. They wind TWO coils, a small on on the sample bottle and a larger one nearby. The turns ratio is picked so that any EM interference will create equal voltage on each coil. Then they hook the coils backwards in series. That way the EM interference is cancelled out. But since the one coil is much closer to the sample bottle, the precession signal is not cancelled.
