Background Information

Allȱmagnetsȱhaveȱmagneticȱfieldsȱbecauseȱtheȱmoleculesȱinȱthemȱhaveȱmovingȱ

electrons,ȱwhichȱcreateȱanȱelectricȱcurrent,ȱandȱaccordingȱtoȱMaxwell'sȱEquations,ȱ

movingȱelectricȱchargesȱwillȱcreateȱaȱmagneticȱfield.ȱBasically,ȱeachȱatomȱactsȱlikeȱ

anȱelectromagnet.ȱAlthoughȱthisȱmagneticȱfieldȱisȱinvisible,ȱitȱcanȱbeȱdetectedȱbyȱ

investigatingȱtheȱNorthȱandȱSouthȱpolesȱofȱaȱmagnet,ȱwhichȱareȱproducedȱwhenȱ

theȱmagneticȱfieldsȱalignȱinȱtheȱsameȱway.ȱWhenȱtwoȱlikeȬpolesȱcomeȱintoȱcontactȱ

withȱoneȱanother,ȱtheyȱrepel.ȱConversely,ȱwhenȱtwoȱunlikeȬpoles

ȱcomeȱintoȱ

contactȱwithȱoneȱanother,ȱtheyȱattract.ȱAsȱaȱresult,ȱstudentsȱwillȱnoticeȱthatȱwhenȱ

theyȱbringȱtheirȱmagnetsȱcloseȱtoȱoneȱanother,ȱtheyȱwillȱeitherȱpushȱapartȱorȱpullȱ

towardsȱoneȱanother,ȱdependingȱonȱhowȱtheyȱorientȱtheȱpoles.ȱ ȱ Magnetsȱwillȱalsoȱattractȱtoȱcertainȱkindsȱofȱmetals,ȱ suchȱasȱiron,ȱnickel,ȱsteel,ȱandȱ
