how to make a high voltage transformer at home?

To make a high voltage transformer at home, you will need a core (often made of iron or ferrite), insulated copper wire for the primary and secondary coils, and a power source. Start by wrapping the primary coil with fewer turns of wire around the core, then wrap the secondary coil with many more turns. Connect the primary coil to your power source, ensuring proper insulation and safety measures. Be cautious, as high voltage can be dangerous.
