Word Origin and History for induction

induction


n.

late 14c., "advancement toward the grace of God;" also (c.1400) "formal installation of a clergyman," from Old French induction (14c.) or directly from Latin inductionem (nominative inductio) "a leading in, introduction," noun of action from past participle stem of inducere "to lead" (see induce).

As a term in logic (early 15c.) it is from Cicero's use of inductio to translate Greek epagoge "leading to" in Aristotle. Induction starts with known instances and arrives at generalizations; deduction starts from the general principle and arrives at some individual fact. As a term of science, c.1800; military service sense is from 1934, American English.

Science definitions for induction

induction

[ ĭn-dŭkshən ]

  1. The process of deriving general principles from particular facts or instances.
  2. A conclusion reached by this process. See Note at deduction.
  1. The creation of a voltage difference across a conductive material (such as a coil of wire) by exposing it to a changing magnetic field. Induction is fundamental to hydroelectric power, in which water-powered turbines spin wire coils through strong magnetic fields. It is also the working principle underlying transformers and induction coils.
  2. The generation of an electric current in a conductor, such as a copper wire, by exposing it to the electric field of an electrically charged conductor.
  3. The building up of a net electric charge on a conductive material by separating its charge to create two oppositely charged regions, then bleeding off the charge from one region.
