individual variable
  ورتنده‌ی ِ تکال   
vartande-ye takâl

Fr.: variable individuel   

In → predicate logic, a variable which represents an unspecified → subject. Individual variables work just as do variables in algebra, they stand in for a value, but have no fixed value of their own. They are represented by lower case letters taken from the end of the alphabet x, y, z; and if additional variables are needed by u, v, w, as well.

Fr.: induire   

To cause or initiate by influence or some means; e.g. → induced current; → induced emission.

Induce, "to lead by persuasions or other influences," from L. inducere "to lead into, persuade," from → in- "in" + ducere "to lead," from PIE *deuk- "to lead" (cf. O.E. togian "to pull, drag," O.H.G. ziohan "to pull").

Darhâxtan, darhâzidan, from dar- "in" + Mid.Pers. hâxtan, hâzidan, "to lead, guide, persuade;" Av. hak-, hacaiti "to attach oneself to, to join;" cf. Skt. sacate "accompanies, follows;" Gk. hepesthai "to follow,"; L. sequi "to follow;" PIE *sekw- "to follow."

induced
  درهازیده، درهاخته   
darhâzidé, darhâxté

Fr.: induit   

Brought about or caused by → induction.

Induced, p.p. of → induce.

induced current
  جریان ِ درهازیده، ~ ِ درهاخته   
jarayân-e darhâzidé, ~ darhâxté

Fr.: courant induit   

Current resulting from the relative motion of a conductor through a magnetic field.

induced ; → current.

induced electric field
  میدان ِ برقی ِ درهازیده، ~ ِ ~ ِ درهاخته   
meydân-e barqi-ye darhâzidé, ~ ~ darhâxté

Fr.: champ électric induit   

An electric field created by the variation of a magnetic field. The induced electric field lines are usually perpendicular to the changing magnetic field that produces them.

induced; → electric; → field.

induced emission
  گسیل ِ درهاخته، ~ ِ درهازیده   
gosil-e darhâxté, ~ darhâzidé

Fr.: émission induite   

The emission of radiation from an atom when it is bombarded by photons. The induced radiation has the same wavelength and direction as the bombarding radiation. Same as → stimulated emission.

induced; → emission.

induced fission
  شکافت ِ درهازیده، ~ درهاخته   
šekâft-e darhâzidé, ~ darhâxté

Fr.: fission induite   

Fission which takes place when a nucleon is bombarded with neutrons or high-energy radiation (gamma rays).

Induced, p.p. of → induce; → fission.

inductance
  درهازندگی   
darhâzandegi

Fr.: inductance   

The property of an electric circuit, or of two neighboring circuits, by virtue of which an electromotive force is induced in one circuit by a change of current in either of them.

Inductance, from induct, from L. inductus, p.p. of → induce + → -ance.

induction
  درهازش   
darhâzeš

Fr.: induction   

1) General: The act of inducing, bringing about, or causing.
2) Electromagnetism: A common term for 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. For more details, see → electromagnetic induction; → electrostatic induction; → magnetic induction.
3) Math.: A method of mathematical proof typically used to establish that a given statement is true of all natural numbers. It is done by proving that the first statement in the infinite sequence of statements is true, and then proving that if any one statement in the infinite sequence of statements is true, then so is the next one.
4) Logic: Any form of reasoning in which the conclusion, though supported by the premises, does not follow from them necessarily. → inductive reasoning.

Verbal noun of → induce.

induction coil
  پیچه‌ی ِ درهازش   
pice-ye darhâzeš

Fr.: bobine d'induction   

A device for producing high-voltage pulses by means of → electromagnetic induction. It consists of a primary coil of a few turns of wire, wound on an iron core, and insulated from a secondary coil of many turns which surrounds it coaxially. The current in the primary, which is interrupted periodically, sets up a magnetic field, first big, then zero. This changing field induces a large voltage in the secondary.

induction; → coil.

induction equation
  هموگش ِ درهازش   
hamugeš-e darhâzeš

Fr.: équation d'induction   

In magnetohydrodynamics, an equation that describes the transport of plasma and magnetic field lines over time:
B/∂t = ∇ x (v x B) + η∇2B,
where B is the → magnetic induction, v is the plasma velocity, and η = (μσ)-1 the → magnetic diffusivity. The first term on the right side represents → magnetic advection and the second term → magnetic diffusion. The induction equation can also be expressed as:
B/∂t = -(v.∇)B + (B.∇)v - B(∇.v),
where the terms of the right-hand side stand for advection, stretching, and compression, respectively. Among these terms, net increase of the field can be done only through the stretching and compression.

induction; → equation.

induction field
  میدان ِ درهازش   
meydân-e darhâzeš

Fr.: champ d'induction   

A component of an electromagnetic field which is the region close to the source (an antenna) where steady-state magnetic and electrostatic forces can be detected. → radiation field.

induction; → field.

  درهازگر، درهازنده   
darhâzgar, darhâzandé

Fr.: bobine d'induction   

A coil of wire used to introduce inductance into an electric circuit.
