Nuclear magnetic resonance explained

Nuclear magnetic resonance explained. Nuclear magnetic resonance (NMR) is a method of physical observation in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field and therefore not involving electromagnetic waves) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus.

What Are the Uses of Magnetic Fields?Sciencing

Atoms have north and south magnetic poles--just like the Earth. Although everything is made of atoms, most things don't behave magnetically because the poles of the atoms are not aligned--the poles point in all different directions. When something aligns the atomic poles in a substance, the substance becomes

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
