Iron wire is a conductor of heat/electricity only and it is impossible to convert heat to electrical energy by using it.
Wrap the iron with many turns of insulated copper wire. Then send a current through the wire. The iron core will become an electro-magnet while the electricity is running.
The iron bar would become more magnetic.
That's not just an iron wire - most materials expand when heated. This is called thermal expansion, and has to do with the fact that molecules move faster when it is hotter.
The strength of an electromagnet depends on: -- The magnitude of the current through the wire. (This depends on the voltage between the ends of the wire.) -- The number of turns of wire in the coil wrapped around the iron core.
Iron ore can be melted by fire, or by focused sunlight.
