Abstract

We have developed a simple, easy to build, and low-cost magnet system for NMR, of which homogeneity is about 4×10^-4 at 57mT, with a pair of two commercially available ferrite magnets. This homogeneity corresponds to about 90Hz spectral resolution at 2.45MHz of the hydrogen Larmor frequency. The material cost of this NMR magnet system is little more than $100. The components can be printed by a 3D printer.
