How is an electrical current generated and detected in NMR?

Question

Quizplus · Accepted Answer

In NMR, a magnetic field is applied to the sample causing the nuclei to align either with or against the field. A radiofrequency pulse is then applied causing the spins to change their orientation. As the spins return to their original orientation, they induce a current in a coil of wire in the detector. This current is then detected and used to generate the NMR spectrum. Option A, B, and D do not correctly describe the process of electrical current generation and detection in NMR.
