A coil of wire in which current is flowing is an electromagnet.
If to that arrangement you add an iron core, then the magnet will get stronger.

Electromagnet
An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
Yes.

When electric current flows, a magnetic field is formed via induction. When copper wire, or another conductor is wrapped around a metal core, it forms an electromagnet.
Yes

Electromagnet
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
A magnet created when electric current flows through a coil of wire is called an electromagnet.
It needs more than an electromagnet. You have an electromagnet with an iron diaphragm in the magnetic field. When the audio current from the amp flows in the electromagnet, the diaphragm moves at the same frequency, making the sound that you hear.
