I am going to make three electromagnets with copper wire of different gauge and length. The three of them have the same iron screw as a ferromagnetic core.
The first ones has a winding of 30 meter of 30 AWG copper wire. The second 20 meters of 28 AWG copper wire and the third 9 meters of 22 AWG copper wire.
Here you can find the characteristics of the different gauges of the american system AWG:
