If you have followed the above steps on how to light a furnace more than twice and the pilot light won't light or won't stay lit when you release the "Reset" button, something is wrong with the furnace and you need to contact a furnace professional.
Don't try to light a furnace without first turning it off. Excess gas can cause serious damage in the home and can also lead to injury. Other than the pilot light, do not attempt to fix your furnace yourself unless you are knowledgeable in furnace repair. Do the same with the other end of the copper wire and the other iron wire. If you heat one of the twisted junctions with a flame and attach the two free iron wires to a volt meter, you will be able to measure a voltage.
In a pilot light, one of the junctions of a thermocouple is sitting in the pilot light's flame. The electricity that is created runs to a small electromagnetic valve and holds it open.
If the pilot light blows out, the thermocouple quickly cools off. It stops generating electricity and the valve closes. To relight the pilot light, you have to push a button that opens the value manually.
Then you light the pilot light and wait for the thermocouple to heat up about 30 seconds. Once it is hot, the thermocouple is generating the electricity needed to hold the value open.
Then you can let go of the button. The problem with pilot lights is that they waste a lot of gas. Therefore, most modern appliances do not have a pilot light. Instead, they use a piezoelectric spark to light the burner.
