The Tesla coil is designed by Nikola Tesla in 1891, is an electrical resonant transformer circuit used used to produce high-voltage, low-current, high frequency alternating-current electricity.A Tesla Coil is a device that creates a high voltage electric field in the air around it when a small input power is provided and allows for wireless power transmission.In this article I am going make you understand tesla coli in just few steps…
Required things to make Tesla Coil
- A length of 30 cm, PVC (the longer the better)
- About 300 feet of 24 AWG copper enameled wire (Secondary Wire)
- Birch Board for base
- 2222A Transistor
- Hookup(primary) Wire – 22Gwg Solid
- 22k ohm Resistor
- Switch and connecting wires
- 9V Battery

Step-by-Step Procedure to make a Tesla Coil
Wind the Secondary First, then the Primary
Put a small slot into the top of the pipe to wrap one end of the wire around, begin to wrap the coil, making sure that you don’t overlap wires or have spaces. Every 20 turns, put a ring of masking tape around the coil to act as a barrier if the coil starts to unravel. Once you complete, wrap a tight piece of tape around the top and bottom of the coil and spray it with 2 or 3 coats of enamel as you can see in the picture below.
Connect the Wireless Power Transmission System
Connect the primary(green) and secondary(golden) to the battery and switch through the transistor and resistor as shown in the circuit diagram. The smaller winding in the diagram is the primary and the longer winding is the secondary. You can additionally add an aluminum sphere on top of the pipe and connect the open end of the secondary to it, which will act as an antenna.
Start Up Your Tesla Coil
Switch ON the device,bring a tube light or a CFL bulb near your wireless power transmission device and enjoy the light show.
NOTE : As it really isn’t safe to run anything this potentially powerful indoors. Be careful, there is a risk of fire.
How Tesla Coil Works ?
The power of the Tesla coil work on the principle called electromagnetic induction, i.e., a changing magnetic field creates an electric potential that compels current to flow. Conversely, the flowing electric current generates a magnetic field. When electricity flows through a wound up coil of wire, it generates a magnetic field that fills the area around the coil.
