production and interrelation of electric and magnetic fields, Maxwell's equations
Four equations, formulated by James Clerk Maxwell, that together form a complete description of the production and interrelation of electric and magnetic fields.

The statements of these four equations are as follows:

  1. Electric field diverges from electric charge.
  2. There are no isolated magnetic poles.
  3. Electric fields are produced by changing magnetic fields.
  4. Circulating magnetic fields are produced by changing electric fields and by electric currents.

Maxwell based his description of electromagnetic fields on these four statements.

1. Having the quality of producing or bringing forth; tending to produce; creative, generative.
2. That which causes or brings about, that results in; causative. Always with of.
3. That which produces readily or abundantly; fertile; prolific.
1. In economics, the rate of output per unit of input, used especially in measuring capital growth, and in assessing the effective use of labor, materials, and equipment.
2. The rate at which radiant energy is used by producers to form organic substances as food for consumers.
redoubt (s) (noun), redoubts (pl)
1. A small, often temporary defensive fortification: Because they were always on the move, the trappers built redoubts to protect themselves and which could be taken down quickly when they relocated themselves.
2. A reinforcing earthwork or breastwork within a permanent rampart: In order to defend themselves even more, the soldiers built a redoubt within the walls of their fortress in order to provide the optimum safety for them.
3. A protected place of refuge or defense: In his room at home, little Tommy built a redoubt with blankets hanging from the framework of his bed so he couldn’t be seen by anyone!
4. An isolated work forming a complete enclosure of any form, used to defend a prominent point: In the book Ted was reading, a small camp and a redoubt were constructed on top of the cliff for the soldiers so that they could safeguard their area.
5. Etymology: from Fr. redoute, from It. ridotto "place of retreat," from M.L. reductus "place of refuge, retreat," from Latin reduct-, past participle stem of reducere, "to lead" or "to bring back".
A small temporary fortification or refuge.
