The coil for the other end is actually a single large
loop that is wrapped around the candle the same way you would if you were
wrapping a rubber band around it. I then coated all the exposed wire and
solder with Liquid Electrical Tape for insulation (not shown).

The end result. The coil can be slid back and forth
along the candle to change the distance between it and the needle tips
embedded inside the candle.
