- the act of inducting; introduction; initiation.
- formal installation in an office, benefice, or the like.
- any form of reasoning in which the conclusion, though supported by the premises, does not follow from them necessarily.
- the process of estimating the validity of observations of part of a class of facts as evidence for a proposition about the whole class.
- a conclusion reached by this process.
- Also called mathematical induction. Mathematics. a method of proving a given property true for a set of numbers by proving it true for 1 and then true for an arbitrary positive integer by assuming the property true for all previous positive integers and applying the principle of mathematical induction.
- a presentation or bringing forward, as of facts or evidence.
- Electricity, Magnetism. the process by which a body having electric or magnetic properties produces magnetism, an electric charge, or an electromotive force in a neighboring body without contact.Compare electromagnetic induction, electrostatic induction.
- Embryology. the process or principle by which one part of the embryo influences the differentiation of another part.
- Biochemistry. the synthesis of an enzyme in response to an increased concentration of its substrate in the cell.

- the act of inducting or state of being inducted
- the act of inducing
- (in an internal-combustion engine) the part of the action of a piston by which mixed air and fuel are drawn from the carburettor to the cylinder
- a process of reasoning, used esp in science, by which a general conclusion is drawn from a set of premises, based mainly on experience or experimental evidence. The conclusion goes beyond the information contained in the premises, and does not follow necessarily from them. Thus an inductive argument may be highly probable, yet lead from true premises to a false conclusion
- a conclusion reached by this process of reasoningCompare deduction (def. 4)
- the process by which electrical or magnetic properties are transferred, without physical contact, from one circuit or body to anotherSee also inductance

Word Origin and History for induction
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.
- The process of initiating or increasing the production of an enzyme or other protein at the level of genetic transcription.
- The period from the first administration of anesthesia to the establishment of a depth of anesthesia adequate for surgery.
- The change in form or shape caused by the action of one tissue of an embryo on adjacent tissues or parts, as by the diffusion of hormones.
- A modification imposed upon the offspring by the action of environment on the germ cells of one or both parents.
- The generation of electromotive force in a closed circuit by a varying magnetic flux through the circuit.
- The process of deriving general principles from particular facts or instances.
- A conclusion reached by this process. See Note at deduction.
- 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.
- 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.
- 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.
A process of reasoning that moves from specific instances to predict general principles. (Compare deduction.)
