- n. The act or an instance of inducting.
- n. A ceremony or formal act by which a person is inducted, as into office or military service.
- n. Electricity The generation of electromotive force in a closed circuit by a varying magnetic flux through the circuit.
- n. Electricity The charging of an isolated conducting object by momentarily grounding it while a charged body is nearby.
- n. Logic The process of deriving general principles from particular facts or instances.
- n. Logic A conclusion reached by this process.
- n. 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.
- n. The act or process of inducing or bringing about, as:
- n. Medicine The inducing of labor, whereby labor is initiated artificially with drugs such as oxytocin.
- n. Medicine The administration of anesthetic agents and the establishment of a depth of anesthesia adequate for surgery.
- n. Biochemistry The process of initiating or increasing the production of an enzyme, as in genetic transcription.
- n. 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.
- n. Presentation of material, such as facts or evidence, in support of an argument or proposition.
- n. A preface or prologue, especially to an early English play.

- n. A process of demonstration in which a general truth is gathered from an examination of particular cases, one of which is known to be true, the examination being so conducted that each case is made to depend on the preceding one; -- called also successive induction.
- n. The property by which one body, having electrical or magnetic polarity, causes or induces it in another body without direct contact; an impress of electrical or magnetic force or condition from one body on another without actual contact.

- n. The act of inducting or bringing in.
- n. Specifically, the introduction of a person into an office with the customary forms and ceremonies; installation; especially, the introduction of a clergyman into a benefice, or the official act of putting a clergyman in actual possession of the church and its temporalities, to which he has been presented: usually performed by virtue of a mandate under the seal of the bishop.
- n. Beginning; commencement; introduction.
- n. In a literary work, an introduction or preface; a preamble; a prologue; a preliminary sketch or scene; a prelude, independent of the main performance, but exhibiting more or less directly its purpose or character: as, the induction to Shakspere's “Taming of the Shrew.”
- n. In logic, the process of drawing a general conclusion from particular cases; the inference from the character of a sample to that of the whole lot sampled.
- n. In physics, the process by which a body having electrical or magnetic properties calls forth similar properties in a neighboring body without direct contact; electrical influence.
- n. Magnetic induction is the flux density in a medium such as iron when subjected to a magnetizing force. It is expressed in terms of a unit called the gauss, namely, the number of lines of force per square centimeter of cross-section of the substance. Induction, thus numerically defined, is usually designated by the letter B; the magnetizing force to which it is due, by the letter H. Induction is frequently determined by winding a ring-shaped piece of the iron to be tested with two coils of wire, the primary and the secondary coil. The secondary coil is connected to a ballistic galvanometer and a known current is suddenly sent through the primary coil. The magnetic field thus established within the iron induces a flow of electricity through the secondary coil and through the galvanometer, which affords a measure of the induction. The relation is expressed by the equation where Q is the quantity of electricity as measured by the deflection of the galvanometer, R is the resistance of the secondary circuit, S is the cross-section of the iron, and n2 is the number of turns of wire in the secondary coil. The relation between induction and the magnetizing force may be expressed graphically by means of a curve, called the curve of induction, in which ordinates represent the values of the induction B and abscissæ the corresponding values of the magnetizing force H. The curve rises slowly for small magnetizing forces and then sharply, for a time, until the iron approaches saturation, after which the slope of the curve diminishes. These changes in the direction of the curve are due to variations in the permeability of the iron, which increases with the magnetizing force, reaches a maximum, and then diminishes again indefinitely. The induction B is not identical with the magnetization I which is defined by the equation
- n. The leading or admission of steam into a cylinder.
- n. In general, the principle that, given any class of terms s, to which belongs the first term of any progression, and to which belongs the term of the progression next after any term of the progression belonging to s, then every term of the progression belongs to s.
