Replacement Electrodes - Ball Tip
Ball Tip Electrode
Enhance your Handheld Tesla Coil (Oudin Coil) with the most versatile attachment in the electrotherapy catalog. The Ball Tip Electrode concentrated spark glass attachment is designed to maximize the "Tesla Effect" by concentrating high-frequency energy to the tip of the electrode, creating a stronger spark .
Whether you are demonstrating the history of the Violet Ray machine or exploring the physics of ionized gas, the Ball Tip electrode provides the most stable and visually stunning plasma glow in the collection.
Why the Ball Tip Shape?
Concentrated Spark Area: The Ball Tip of the electrode allows for direct precision 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 Ball Tip 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 Concentrated Spark of the Ball Tip to demonstrate how the human body acts as a capacitor, drawing plasma filaments toward the glass surface upon proximity.
Wireless Power: The broad field generated by the ball tip head is ideal for "charging" nearby handheld gas or spectrum tubes without 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 Concentrated Spark of the Ball Tip 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.
