induction
When a magnet is passed through a coil of wire, it produces an electric current. The direction of the flow of the current depends on the direction in which the magnet moves. In the top diagram the current flows from right to left. In the bottom diagram the current flows from left to right.

## in·duc·tion

(ĭn-dŭk′shən)
n.
1.
a. The act or an instance of inducting.
b. A ceremony or formal act by which a person is inducted, as into office or military service.
2. Electricity
a. The generation of electromotive force in a closed circuit by a varying magnetic flux through the circuit.
b. The charging of an isolated conducting object by momentarily grounding it while a charged body is nearby.
3. Logic
a. The process of deriving general principles from particular facts or instances.
b. A conclusion reached by this process.
4. Mathematics A two-part method of proving a theorem involving an integral parameter. First the theorem is verified for the smallest admissible value of the integer. Then it is proven that if the theorem is true for any value of the integer, it is true for the next greater value. The final proof contains the two parts.
5. The act or process of inducing or bringing about, as:
a. Medicine The inducing of labor, whereby labor is initiated artificially with drugs such as oxytocin.
b. Medicine The administration of anesthetic agents and the establishment of a depth of anesthesia adequate for surgery.
c. Biochemistry The process of initiating or increasing the production of an enzyme, as in genetic transcription.

a. 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
b. a conclusion reached by this process of reasoning. Compare deduction4
5. (General Physics) the process by which electrical or magnetic properties are transferred, without physical contact, from one circuit or body to another. See also inductance
6. (Biology) biology the effect of one tissue, esp an embryonic tissue, on the development of an adjacent tissue
7. (Biochemistry) biochem the process by which synthesis of an enzyme is stimulated by the presence of its substrate

induction
When a magnet moves through a conducting coil, it induces (generates) an electric current. The direction of the flow of the current depends on the direction in which the magnet moves. In the diagram on the left, the current runs from right to left. In the diagram on the right, the current runs from left to right.
