Iron rod is a conductive material. You will get electrocuted if you touch a live wire with any conductive material like iron rod. It could be fatal to do so.
The metal rod would conduct electricity and, if you are grounded, you could be electrocuted, injured or killed.
The live wire
If it is a push on type of wire connector you should be able to use a small bladed screwdriver that fits into the slot.
so you know which wire is which! - live, neutral or earth
No. You should use a wire with the best electric conductivity (copper or silver) and wrap it around a (soft) iron core. The wire creates the magnetic field, the iron core concentrates it and turns into a magnet when a voltage is applied to the wire. Iron has rather poor conductivity and malleability so is not suited as the coil of an electromagnet.
You connect the fuse to the live wire as it is the one with the potential difference of 220V and in case of short circuit current will blow out here
The live wire
You can use a wire tester to determine if a wire is live. You can also touch the positive wire on the ground wire, if the wire produces a spark it is live.
Same side as the fuse.

The ability to be drawn into a thin wire is a property known as ductility. Iron has ductility.

You should never touch a person in contact with live wire because the electricity will get run thru the body ad also get to you.
The physical shape doesn't influence what is is chemically. Pure iron (Fe) is an element regardless of the shape. Strictly speaking iron wire is probably an alloy. Mostly iron, but with a dab of other elements to make it stronger and easier to draw into a wire.
first, you have to have a ferromagnetic core, like an iron bolt. then, you wind a magnetic wire around it. the thicker the winding, the stronger the magnet. the tips of the wire should be protruding so you can connect it to a source. skin the tips of the wire, too. connect the wire to a dc source and you got an electromagnet.

yes
A fuse should be connected in the live wire, before reaching the appliance.
