====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Set up the Tesla coil securely on an insulated surface.  
  - Ensure proper grounding of the coil and that all safety barriers are in place.  
  - Power on the Tesla coil to begin generating a high voltage, high frequency electric field.  
  - Hold a fluorescent tube or neon lamp near the coil without touching the coil itself.  
  - Observe the lamp glowing due to induced currents from the electric field.

====Variations====
  * Test different types of lamps such as neon signs, compact fluorescent bulbs, or larger fluorescent tubes.  
  * Vary the distance of the lamp from the Tesla coil to observe how brightness decreases with distance.  
  * Use different shapes or sizes of Tesla coil top-loads to see how field strength and range are affected.



====Safety Precautions====
  * Keep people with pacemakers or implanted devices at a safe distance.  
  * Maintain good ventilation to avoid ozone buildup from the sparks.  
  * Do not touch the Tesla coil or the lamp while the coil is operating.  
  * Keep sensitive electronics far away to prevent interference or damage.




====Questions to Consider====
  * Why does the lamp glow even though it is not connected by wires? (The Tesla coil produces a strong oscillating electric field that excites the gas inside the lamp, causing it to emit light.)  
  * How does the brightness change as you move the lamp further from the Tesla coil? (It becomes dimmer because the strength of the electric field decreases with distance.)  
  * What real-world technologies are based on wireless power transfer like this demonstration? (Examples include wireless phone charging and some proposed wireless power transmission systems.)
