copper wire is used in electromagnets.
what kind of wire is used in electromagnets?
copper
magnet wire





























magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. it is used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire.





























the wire itself is most often fully annealed, electrolytically refined copper. aluminium magnet wire is sometimes used for large transformers and motors. the insulation is typically made of tough polymer film materials rather than enamel, as the name might suggest.

the circular arrangement of electromagnets is divided into groups, each group called a phase, and there is an equal number of electromagnets per group. the number of groups is chosen by the designer of the stepper motor. the electromagnets of each group are interleaved with the electromagnets of other groups to form a uniform pattern of arrangement. for example, if the stepper motor has two groups identified as a or b, and ten electromagnets in total, then the grouping pattern would be ababababab.
