Square Magnet Wire Properties

Square Magnet Wire

Square magnet wire is useful where space constraints are concerned. When formed into a coil an equivalent amount of square wire put in a coil can be placed in a tighter coil configuration than the same amount of round wire. This enables engineers to create compact coils and small motors that deliver more power in less space.
