This interaction leads to two phenomena: shielding, where the nucleus experiences a lower magnetic field, and deshielding, where it experiences a higher field.

It highlights NMR techniques relevant in molecular physics, material science, and medical imaging (MRI). Key concepts include the intrinsic spin of nuclei, magnetic field interactions, resonance frequency, chemical shifts, and the n+1 rule for peak multiplicities in NMR spectra.

Thomson's work on electrons. It details how power outages disrupt electricity flow and describes Thomson's experiments with cathode ray tubes, which identified cathode rays as streams of electrons. His findings, including their deflection by magnetic fields and a consistent charge-to-mass ratio across substances, were pivotal in advancing atomic theory.
