  • 4.3. BUILD A TRANSFORMER1514.3Build a transformerPARTS AND MATERIALS• Steel flatbar, 4 pieces• Miscellaneous bolts, nuts, washers• 28 gauge ”magnet” wire• Low-voltage AC power supply”Magnet wire” is small-gauge wire insulated with a thin enamel coating. It is intended tobe used to make electromagnets, because many ”turns” of wire may be wrapped in a relativelysmall-diameter coil. Any gauge of wire will work, but 28 gauge is recommended so as to makea coil with as many turns as possible in a small diameter.CROSS-REFERENCESLessons In Electric Circuits, Volume 2, chapter 9: ”Transformers”LEARNING OBJECTIVES• Effects of electromagnetism.• Effects of electromagnetic induction.• Effects of magnetic coupling on voltage regulation.• Effects of winding turns on ”step” ratio.SCHEMATIC DIAGRAMTransformerILLUSTRATION
