 **Winding** or **coil** - a length of [[wire]] or [[conductor]] wound in a specific shape, in order to achieve specific [[magnetism|magnetic]], [[electricity|electric]] or [[electromagnetism|electromagnetic]] properties of such configuration.  **Winding** or **coil** - a length of [[wire]] or [[conductor]] wound in a specific shape, in order to achieve specific [[magnetism|magnetic]], [[electricity|electric]] or [[electromagnetism|electromagnetic]] properties of such configuration. 
  
-Each loop of a winding is known as a [[turn]], and the number of turns is one of the basic characteristics of a winding.

In majority of designs the turns must be [[electrical insulator|electrically isolated]] from each other, as well as from the rest of the device (e.g. [[magnetic core]]).

 The conductor in a power-related winding is typically required to carry a substantial amount of [[electric current]] (e.g. for generation of [[magnetic field]]), so it has to have a sufficient [[cross-section area]]. Conversely, sensing coils might carry only very small signal, so they can be made from very thin conductors.   The conductor in a power-related winding is typically required to carry a substantial amount of [[electric current]] (e.g. for generation of [[magnetic field]]), so it has to have a sufficient [[cross-section area]].
