There are a lot of turns in the secondary. Think of a tesla coil as a relaxation oscillator using a spark gap. When the gap arcs, this drives the primary coil with a abrupt pulse. This couples into the secondary, which is resonant in the medium wave frequencies. > Also, how high is high frequency for an average Tesla coil? 100 Khz to 1 Mhz, the bigger the coil the lower the frequency. In this range, you have the option of interfering with aeronautical beacons, a maritime distress frequency, and all of your neighbors AM radios. markz@ssc.uucp
