Experimental System of CW NMR Advanced Model for Advanced Physics Lab

The Experimental System of CW NMR Advanced Model for Advanced Physics Lab is designed for advanced studies of nuclear magnetic resonance phenomena and precision measurement of nuclear magnetic properties. The system combines a highly homogeneous electromagnet, precision oscillator, and advanced measurement instruments to provide reliable and repeatable experimental results. The apparatus enables students to investigate resonance behavior of hydrogen and fluorine nuclei, determine important nuclear parameters, and study the influence of magnetic field homogeneity on signal quality. The open magnet structure allows convenient specimen handling, while the high field uniformity ensures clear resonance signals and enhanced observation of coda wave phenomena. This system serves as an excellent educational and research platform for advanced physics laboratories, offering practical experience in magnetic resonance techniques, nuclear spectroscopy, and precision magnetic field measurements.
