How does a Ruhmkorf coil produce radio waves?

Click For Summary
SUMMARY

The Ruhmkorf coil generates radio waves through a series of interruptions that trigger a diminishing train of RF pulses. The base frequency of these pulses is determined by the inherent LC circuit of the setup. The discussion highlights that the spark frequency, interruptor frequency, and radio signal frequency do not match, indicating a complex interaction of frequencies. Users are advised to exercise caution due to the potential disruption of the local RF environment caused by the coil's operation.

PREREQUISITES
  • Understanding of LC circuits and their role in frequency generation
  • Knowledge of radio frequency (RF) pulse behavior
  • Familiarity with spark ignition systems and their effects on RF
  • Experience with basic electrical components, such as a 9V DC power supply
NEXT STEPS
  • Research the principles of LC circuit resonance and frequency determination
  • Explore the effects of RF interference in electronic systems
  • Learn about the operation and applications of Ruhmkorf coils
  • Investigate methods to mitigate RF noise in experimental setups
USEFUL FOR

Electronics enthusiasts, physics students, and hobbyists interested in radio frequency generation and the practical applications of Ruhmkorf coils.

Does the spark frequency = the interruptor frequency = radio signal frequency.
From the sources I have found these frequencies don't seem to match.
We use a 9V DC one at school.
Many Thanks

Each 'interruption' triggers a diminishing train of RF pulses with base frequency set by the set-up's inherent LC. There will also be a strew of octaves due to the initial 'kick'. Like an old lawnmower, bike etc with un-damped spark ignition, it makes a total mess of local RF environment, so please use due care.
