If you introduce the rod with the round strips into the flame of a candle, the paper will not catch fire. The fire will lick the paper but not burn down until the iron rod becomes hot. This is because iron rod just like any other metal is a good conductor of heat, it leads away the heat obtained by paper from the candle flames. Replace the iron rod by a wooden stick and paper will burn because wood is a poor conductor of heat. With copper rod the experiment is more successful.

The paper strip will not burn when wrapped tightly around the iron rod and rotated continuously while trying to burn with a candle. This is because the constant rotation disperses the heat, preventing the paper from reaching its ignition temperature. The metal rod acts as a heat sink, absorbing and dissipating the heat away from the paper.
