  "term": "Dipole field",
  "field": "Oil and gas",
  "definition": "A magnetic or electric field generated by two equal and opposite poles or charges separated by a small distance. The Earth's main magnetic field approximates a dipole field, with north and south magnetic poles, which is the basis for magnetic surveying methods used in exploration. In borehole logging, dipole acoustic tools generate a flexural wave that is sensitive to shear-wave velocity, even in slow formations.",
