Replacement Electrodes - Mushroom
Mushroom Electrode
Enhance your Handheld Tesla Coil (Oudin Coil) with the most versatile attachment in the electrotherapy catalog. The Mushroom Electrode is the iconic, wide-surface glass attachment designed to maximize the "Tesla Effect" by spreading high-frequency energy across a broader area.
Whether you are demonstrating the history of the Violet Ray machine or exploring the physics of ionized gas, the Mushroom electrode provides the most stable and visually stunning plasma glow in the collection.
Why the Mushroom Shape?
Broad Surface Area: The curved, flat face of the electrode allows for uniform contact and consistent discharge.
It is perfect for demonstrating the "Skin Effect" of high-frequency electricity.
Vibrant Gas Ionization: Filled with specialized rarefied gases (typically Neon for a fiery orange-red or Argon for a deep violet), the electrode glows brilliantly when the wand’s 20kV to 48\kV output excites the gas molecules inside.
Vacuum Discharge Demo: Use the Mushroom electrode to show how electrical potential behaves differently in a vacuum versus open air, creating a soft, ethereal "violet ray" glow rather than a jagged spark.
Historical & Educational Applications
In the history of Jacques-Arsène d’Arsonval and Paul Marie Oudin, the mushroom head was the primary tool used in early 20th-century electrotherapy.
History Demos: Recreate the exact experience of a 1920s "Violet Ray" treatment session, explaining how early physicians believed these high-frequency currents could stimulate circulation.
Physics of Capacitance: Use the mushroom head to demonstrate how the human body acts as a capacitor, drawing the plasma filaments toward the glass surface upon proximity.
Wireless Power: The broad field generated by the mushroom head is excellent for "charging" nearby handheld gas tubes or spectrum tubes without making physical contact.
Technical Compatibility
Fit: Designed for standard 11mm (approx. 7/16") or 12mm wand sockets (ensure your Oudin coil's socket size before purchase).
Material: Hand-blown, high-durability tempered glass.
Input Requirement: Optimized for use with the 120V 60Hz Oudin Coil system.
Pro-Tip: When using the Mushroom electrode for demonstrations, always start the wand at the lowest voltage setting on the dial and gradually increase it to find the "sweet spot" where the gas inside the glass fully ionizes without overstressing the coil.
