That schematic is nonsense and will not work even if the LED, which is probably needed, is wired in. It has no realistic feedback path to make it oscillate and the transistor it mentions is far too small to work properly. Don't trust everything you see on the Internet, a lot of it is incorrect or only works by chance.
Connect the bottom of the existing 275 turn coil to the negative line.
Add another coil, try 3 turns but it may need more, at the bottom end of the 275 turn coil, near to the existing 33 turn coil. Wire one end to the base of the transistor, the other end to the junction of the 22K resistor and the LED. Wire the LED the other way around so the cathode goes to the negative line. Try it, if it doesn't work, swap the ends of the new coil over.
