Resolution is affected by the strength of the B0 magnetic field. The j coupling (distance between lines in a quartet for instance) is a constant value in Hz. However the place that the lines appear is not. Increasing the magnet increases the distance between features while keeping the j coupling from overlapping (thus allowing independent, resolved peaks

In the context of nuclear magnetic resonance imaging (NMRI), resonance refers to the absorption of radiofrequency energy by atomic nuclei in a magnetic field. When the applied radiofrequency matches the resonant frequency of the atomic nuclei, it causes them to resonate and emit signals that can be detected and used to create images of the internal structures of the body.

No, a nuclear reactor produces thermal energy and ionising radiation, no magnetic effects.
Nuclear Magnetic Resonance is often used in the Radiology modality of MRI, which stands for Magnetic Resonance Imaging. Nuclear Magnetic Resonance is an alternative to radiation producing techniques such as the traditional Anode/Cathode X-ray tube. NMR is used to help to visualize patient anatomy and pathology without delivering the harmful effects of ionizing radiation used in other modalities.

Infrared (IR) spectrum peaks are broader than nuclear magnetic resonance (NMR) spectrum peaks because IR is sensitive to molecular vibrations which are affected by multiple bonds in different environments, leading to a range of frequencies being absorbed. On the other hand, NMR is based on the magnetic properties of nuclei in a fixed magnetic field, resulting in specific resonances corresponding to unique atomic environments, hence producing sharper peaks.
