NMR Simulator

This simulator uses a Plexiglas frame on which are mounted a pair of hand-wound electromagnets (optional), a switch, a resistor and a 9-volt battery holder. The atomic nuclei are represented by orienteering compasses, drained of their fluid and placed on the top surface of the Plexiglas frame. To the side of the simulator is placed a linear array of three strong permanent magnets.
