Main Functions / প্রধান ফাংশন
1. Tesla Coil Arc Demonstration
After correct assembly, the secondary coil generates a high-frequency, high-voltage electric field capable of producing a small visible discharge at the top electrode.
2. Music Plasma Speaker
A compatible audio source can be connected to the circuit. The electrical discharge is modulated by the audio signal, allowing the arc to reproduce audible sound.
3. Wireless Power Transmission
A small receiving coil with LED can be placed close to the operating Tesla coil. Energy is transferred through the alternating electromagnetic field and can illuminate the LED without a direct wired connection.
4. Fluorescent Lamp Demonstration
A fluorescent or suitable discharge lamp brought near the operating coil may glow due to the strong high-frequency electric field.

Using higher voltage generally increases heating and electrical stress on the circuit.
Wireless Power Demonstration
One of the interesting experiments possible with this Tesla coil is resonant wireless energy transfer.
A receiving coil connected to an LED can be positioned near the transmitter coil. When the Tesla coil is powered, the alternating electromagnetic field can induce energy in the receiving coil and illuminate the LED.
This provides a simple visual demonstration of:
• Electromagnetic induction
• Resonance
• Wireless energy transfer
• High-frequency electromagnetic fields

Important Safety Information / গুরুত্বপূর্ণ নিরাপত্তা নির্দেশনা
⚠️ This is a high-frequency, high-voltage experimental device.
Although the input supply is low-voltage DC, the Tesla secondary produces high-voltage RF energy. It should not be treated as a harmless toy.
⚠️ Do not intentionally touch the discharge electrode or arc while operating. Burns or unpleasant RF exposure may occur.
⚠️ Keep fingers, conductive objects and loose wires away from the top of the Tesla coil.
