Experimental System of CW NMR Advanced Physics Experiment

This Continuous-Wave Nuclear Magnetic Resonance (CW-NMR) experiment system is designed to study the fundamental principles of nuclear magnetic resonance using a high-homogeneity permanent magnet and precision electromagnetic field control. The system enables students to observe the NMR phenomenon of hydrogen and fluorine nuclei, investigate the effects of paramagnetic ions, and measure important nuclear parameters such as the spin magnetic ratio and Landé g-factor. The low-power electromagnetic field design minimizes heating, allowing continuous operation for extended laboratory sessions. Optional Accessory: Frequency Meter. External Equipment Required: Oscilloscope (not included). Physics Lab Experiments from Atico Exports.
