/ (ɪnˈdʌkʃən) /

noun

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

logic

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 another See also inductance

biology the effect of one tissue, esp an embryonic tissue, on the development of an adjacent tissue

biochem the process by which synthesis of an enzyme is stimulated by the presence of its substrate

maths logic

a method of proving a proposition that all integers have a property, by first proving that 1 has the property and then that if the integer n has it so has n + 1

[ ĭn-dŭk′shən ]

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.
