One source is to buy a roll of wire from an electronics store

Tesla coil with spiral primary coil. Relevant parts for primary circuit. Since high voltage is involved, you want to use thick wire. Thin wire will tend to leak charge to the air. In the photo below is some 16 gauge (AWG) wire. Another source is household wiring, available in some hardware stores.
