Demonstrationsversuch zur Kernresonanz mit vorpolarisierter, kontinuierlich strömender Flüssigkeit

Summary

The experiment demonstrates the influence of the magnetic induction on the polarization of nuclear spins. The sample used is distilled water which passes through a strong magnetic field where it becomes polarized. Afterwards the water is led into a weak magnetic field where an energy exchange occurs between the proton spins and the R.F.-circuit of a spin detector while some of the initial polarization is still present. The prepolarizing process ensures better conditions for magnetic resonance experiments than the usual static method.
