Recently,vehicleshavebeendevelopedthatrunonelectricityand
usemagnetism.Therearecoilsinlocomotivesandsometrainbodies
havemagnets.Bysendinganelectriccurrenttothem,wecanswitch
theN-poleandS-poleoftheelectromagnet.Thenatraincanmoveby
theforcesofattractionandrepulsion.
Also,bychangingtheintervaltimeoftheswitchingbetweentheN-pole
andS-pole,itispossibletoadjustthespeedofthecar.Comparedtoa
conventionaltrain,alinearmotorcarcanmovewhilefloating.Because
thereisnothingtouchingtheground,thereislessvibration.Forthis
reason,ithasattractedpositiveattentionasameansoftransportthatis
bothfastandcomfortable.

Whenitstops,the
polesaresetto
attractbetweenthe

Thenswitchtherail's

Throughthesesteps,thelinearmotorcarisabletorun.
