Here we allow students to face a real MR<br \/>\nsetup based on the Earth&#8217;s magnetic field. We address the applied side of teaching MR using a device<br \/>\nthat is affordable and that proves to be sufficiently robust, at universities in Orsay, France, and<br \/>\nSan Sebastian, Spain, in experimental practicals at undergraduate and graduate levels. We<br \/>\nspecifically present some of the advantages of low field for measuring R 2 relaxation rates,<br \/>\nreaching a power of separation of 1.5 \u03bc mol on Mn(II) ions between two water bottles each of half a<br \/>\nliter.
