... SUMMARY The general phenomenon of nuclear magnetic resonance is introduced using both a classical and a quantum mechanical perspective. This provides the basis for understanding measurable and informative NMR parameters: chemical shift, spin-spin splitting, linewidths, relaxation, the nuclear Overha ...

... And since the surface A can be drawn anywhere in the hollow region, the electric field must be zero everywhere in the hollow region. The shell therefore shields the hollow region from external fields and charges. We have shown: Concept 5. The electric field everywhere inside the hollow region of a c ...

Complete electromagnetic multipole expansion including toroidal
... The electromagnetic multipole expansion presented in this paper is complete on two accounts: i) It is valid for all points in space, and ii) it recognizes the existence of toroidal moments. The electromagnetic field due to alternating poloidal currents in a toroidal solenoid is evaluated exactly via ...
