The definition of induction is the act of causing something to happen or an initiation ceremony.noun
- An example of induction is causing a woman to go into labor.
- An example of induction is a ceremony welcoming new members of the military.
- an inducting or being inducted; installation, initiation, etc.
- Archaic an introduction; preface or prelude
- an inducing, or bringing about
- a bringing forward of separate facts or instances, esp. so as to prove a general statement
- Embryology the influence of one tissue upon the development of adjacent tissue, as by the diffusion of a chemical substance to nearby tissue
- Logic reasoning from particular facts or individual cases to a general conclusion; also, a conclusion reached by such reasoning
- Math. a method of proving a theorem which holds true for all whole numbers greater than or equal to some first number, by demonstrating that it holds true for the first number and by showing that, if it holds true for all the subsequent numbers preceding a given number, then it must hold for the next following numberin full mathematical induction
- the act or process by which an electric or magnetic effect is produced in an electrical conductor or magnetizable body when it is exposed to the influence or variation of a field of force
- the transference of the explosive mixture of air and fuel from the carburetor to the cylinder of an internal-combustion engine

- 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.
- 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.
- Logic a. The process of deriving general principles from particular facts or instances.b. A conclusion reached by this process.
- 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.
- 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.d. Embryology The process by which one part of an embryo causes adjacent tissues or parts to change form or shape, as by the diffusion of hormones or other chemicals.
- Presentation of material, such as facts or evidence, in support of an argument or proposition.
- A preface or prologue, especially to an early English play.
induction - Computer Definition
The process of generating an electric current in a circuit from the magnetic influence of an adjacent circuit as in a transformer or capacitor.Electrical induction is also the principle behind the write head on magnetic disks and earlier read heads. To create (write) the bit, current is sent through a coil that creates a magnetic field which is discharged at the gap of the head onto the disk surface as it spins by. To read the bit, the magnetic field of the bit "induces" an electrical charge in the head as it passes by the gap. See inductor.

induction - Cultural Definition
An effect in electrical systems in which electrical currents (see also current) store energy temporarily in magnetic fields before that energy is returned to the circuit.
A process of reasoning that moves from specific instances to predict general principles. (Compare deduction.)
induction - Medical Definition
- 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.
induction - Science Definition
- a. The process of deriving general principles from particular facts or instances.b. A conclusion reached by this process. See Note at deduction.
- a. 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.b. 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.c. 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.
When a magnet moves through a conducting coil, it induces a voltage across the coil that can cause electric current to flow. The direction 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 moves from left to right.
