solenoid
  سولوار   
sulvâr

Fr.: solénoïde   

A long coil of insulated copper wire containing a large number of close turns. The strength of magnetic field produced by a current carrying solenoid is directly proportional to the number of turns in the solenoid and to the strength of current in the solenoid. It also depends on the nature of "core material" used in making the solenoid. The use of → soft iron rod as core in a solenoid produces the strongest magnetism.

From Fr. solénoïde "pipe-shaped," from Gk. solen "pipe, channel" + combining form of eidos "form, shape," → -oid.

Sulvâr, from sul "pipe, gutter," Lori sil, Sangesari sula, Šahmirzâdi solla, Tabari seltek, may be cognate with Gk. solen, as above, + -vâr, → -oid.

soliton
  سولیتون   
soliton

Fr.: soliton   

Math., Physics: A solution of a certain type of partial differential equation that represents a solitary wave. A soliton is a self-reinforcing wave that maintains its shape while it travels at constant speed. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium.

solstice
  خوریستان   
xoristân (#)

Fr.: solstice
