A bobbin is a spindle or cylinder, with or without flanges, on which wire, yarn, thread or film is wound.[1] Bobbins are typically found in sewing machines, cameras, and within electronic equipment. In non-electrical applications the bobbin is used for tidy storage without tangles. In electrical applications a coil of wire carrying a current has important magnetic properties. As used in spinning, weaving, knitting, sewing, or lacemaking, the bobbin provides temporary or permanent storage for yarn and may be made of plastic, metal, bone or wood.
