Weeeelllll!! It doesn't always warm up, depends on the size and type of wire and how much current is flowing.
60 amps through a piece of 10amp fuse wire will melt it instantly, but 1 amp through a piece of 16²mm cable will have no effect.

1) warms up as was mentioned.
2) a magnetic field builds up proportional to the current through it.
3) electrons inside the wire will drift at a very slow speed through the wire. while electric current flows through a wire at near the speed of light, the individual electrons that conduct the current really move relatively slowly. In DC they all move in one direction, and in AC they move back and forth.

It gets warm depending on the type of wire and it's resistance. That's why you have wires used to transfer electricity to an electric heater, then different 'wires' used to produce the heat.
Also a magnetic field forms around the wire, but not substantial.

It warms up and a magnetic field forms around the wire.

electrons and protons orbit an atom if u introduce another proton u have unballanced the number of protons around the atom so it moves 2 the next atom and the same happens introduce lots of em and u have electricity

In addition to earlier answers, if the current is alternating then radio waves will be emitted.
