==Key Stage 1==
===Meaning===
[[File:Wires.png|right|300px|thumb|These wires can be used to build a circuit.]]
'''Wires''' are long pieces of metal covered in [[Plastic (Material)|plastic]].
===About Wires===: Wires carry electricity which can hurt you.: You should not touch a wire unless an adult says it is safe.: If the [[File:ElectricalWires.pngPlastic (Material)|right|300px|thumb|Textplastic]]has come off a wire and you can see the metal you should tell an adult as soon as you can.
Text==Key Stage 2=====Meaning===A '''wire''' is a long piece of metal used to carry electricity. It is usually covered in [[Plastic (Material)|plastic]] to prevent [[Electrical Shock|electrical shocks]].
: Singular [[Noun]]: '''TitleWire''': Plural [[Noun]]: '''TitlesWires''': [[Verb]]: '''To title''': [[Adjective]]: '''Titlewire'''
===About TitleWires===Text: '''Wires''' are used to connect [[Electrical Component|electrical components]] together.: Electricity flows through the metal in the '''wires'''.: A '''wire''' is usually covered in [[Plastic (Material)|plastic]] for safety. The [[Plastic (Material)|plastic]] is safe to touch, but if you can see the metal then it is dangerous and could electrocute you if you touched it.: '''Wires''' come in many sizes. The thicker the wire the more electricity it carries and the more dangerous it is.: The [[metal]] inside a '''wire''' is an [[Electrical Conductor|electrical conductor]] which means electricity can pass through it easily.: The [[Plastic (Material)|plastic]] covering the '''wire''' is an [[Electrical Insulator|electrical insulator]] which means electricity does not pass through it very easily.
==Key Stage 3=Examples====Meaning===A '''wire''' is a long, thin piece of [[metal]] that allows electricity through it. ===About Wires==={: '''Wires''' are used to connect [[Electrical Component|electrical components]] together.: [[Electron]]s flow through the [[metal]] in the '''wires''' as an [[Electrical Current|electrical current]].: A '''wire''' is usually covered in an [[Electrical Insulator|insulator]] such as [[Plastic (Material)|plastic]]. This prevents [[Electrical Current|electrical current]] leaving the [[wire]] when it is touched by an [[Electrical Conductor|electrical conductor]]. This also prevents [[electrocution]].: The [[metal]] inside a '''wire''' is an [[Electrical Conductor|electrical conductor]] which means electricity can pass through it easily.: The [[Plastic (Material)|plastic]] covering the '''wire''' is an [[Electrical Insulator| classelectrical insulator]] which means electricity does not pass through it very easily. ==Key Stage 4=====Meaning===A '''wire''' is a long, thin piece of [[metal]] that allows [[electricity]] through it. ===About Wires==="wikitable": '''Wires''' are used to connect [[Electrical Component|-electrical components]] together.: [[Electron]]s flow through the [[metal]] in the '''wires''' as an [[Electrical Current|electrical current]].: A '''wire''' is usually covered in an [[Electrical Insulator|insulator]] such as [[Plastic (Material)|plastic]]. This prevents [[Electrical Current|electrical current]] leaving the [[Filecircuit]] when the [[wire]]s are touched. This also prevents [[electrocution]].: [[Wire]]s are [[heated]] by an [[Electrical Current|electrical current]] passing through them.:Picture[[Wire]]s are designed to be a low [[Electrical Resistance|resistance]] in order to allow an [[Electrical Current|electrical current]] through them without losing too much [[energy]] by [[heating]] the [[wire]]s.png ===Magnetic Field of a Wire===: When there is a [[Electrical Current|centercurrent]] in a [[wire]] the [[wire]] has a [[Magnetic Field|200pxmagnetic field]]which acts around that [[wire]]. {||[[File:PictureMagneticFieldLinesWire.png|center|200px300px]]|style="padding: 20px; height:20px; width:300px; text-align:left;" |The [[Magnetic Field|Textmagnetic field]] of a [[Electrical Current|Textcurrent]] carrying [[wire]].

|[[File:PictureRightHandThumbRule.png|center|200px300px]]|style="padding: 20px; height:20px; width:300px; text-align:left;" |The direction of the [[File:Picture.pngMagnetic Field|centermagnetic field]] can be shown by the 'right hand thumb rule' with thumb pointing in the direction of the [[Electrical Current|200pxcurrent]]the fingers will wrap around in the direction of the [[Magnetic Field|-|Text|Textmagnetic field]].

The strength of the [[Magnetic Field|magnetic field]] of a [[wire]] depends on:
*The [[Electrical Current|current]] in the [[wire]] - The greater the [[Electrical Current|current]] the stronger the [[Magnetic Field|magnetic field]].
*The distance from the [[wire]] - The greater the distance from the [[wire]] the weaker the [[Magnetic Field|magnetic field]].
