| Proton Magnetometer |
| Description: Proton Magnetometer
by Leslie Huggard
This is one of the earliest magnetometer project articles I've found, yet it is one that is still hard to beat. Unlike the Wadsworth design published in the Feb. 1968 Scientific American, this mag has an automatic mode so you don't have to manually switch the coils. The only improvements that hobbyists have been toying with are toroidal coils and maybe noise improvements in the first gain stage.
This article was published in the October, 1970 issue of Practical Electronics. Practical Electronics merged with Everyday Electronics to become Everyday Practical Electronics, a popular electronics magazine that is owned by UK publisher Wimborne Publishing, Ltd.

Hi,
I am interested in building an EFNMR spectroscope (using proton precession - just like a PPM except that I will be looking for the "chemical shift" in the return signal) - is this Sci. Am. article useful? (I have to make another four posts before this site will allow me to download it) | Bytarantuna

Hi,
I have found this forum by accident, browsing Internet and looking for sites where I could find some practical advice how to build a proton precession magnetometer. I know some physics -- actually, I am an experimental physicist, but in an area that has little in common with NMR (nuclear reactors, neutron scattering is the area of my expertise). However, I'd like to built a proton precession magnetometer as a hobby project. Could you give me some advice, what is best to begin with? Is the article by L. C. Strong in the February 1968 issue of Sc. Am. a good "tutorial" for beginners like me? (on the Web I found many references to that article, but I have not yet read it). Or could you guys recommend something else good for "novices" with much enthusiasm, but zero experience? I'll appreciate your help.
I know the basic THEORY of NMR, but not much beyond -- advanced things such as the "spin-echo" about which NMR people talk all the time is a complete mystery to me. Not mentioning the Overhauser Effect, which is even a higher level of art than spin echo. I happen to know Al Overhauser, who discovered that effect many years ago -- I did some neutron scattering work for him, but that project had nothing to do with the Overhauser Effect, unfortunately.
