Is this a song lyric? Some Buddhist koan? A "which came first" -type riddle ? ? ?
An iron bar is a conductor of electricity due to its ability to allow the flow of electrons. Iron has a high electrical conductivity compared to insulators like rubber or plastic.
1kg of iron contains more matter and occupies less space than 1kg of cotton. Iron is denser than cotton, so it has a higher mass-to-volume ratio.
The iron bar would become magnetized when inserted into a wire coil carrying an electric current. This is because the electric current induces a magnetic field in the coil, which in turn magnetizes the iron bar.
The weight of the objects is not provided, so it is impossible to determine which is heavier based on the information given.
A relay is made up of a coil with an iron core and a movable iron bar. The movable iron bar in a relay is called a switch.

A cotton bag will take a few months to biodegrade/decompose.

you have to mine iron ore then put it in a furnace and you will get an iron bar called an iron ingot.
Usually, cotton cloth is pressed with an iron.
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
From best to worse, it would be glass, plastic, cotton and iron.
Cotton/Wool
an iron bar is harder to bend.
