iron
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.

This causes the power of the electromagnet to be increased.
This causes the power of the electromagnet to be increased.
Coils of wire
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.
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
A coil of wires wrapped around a core is an electromagnet.

It makes an electromagnet.
"Electromagnet"
I believe that it's spelled electromagnet. An electromagnet is produced by electricity flowing through a wire wrapped around a needle 30 or more times.
