I think that the best electro magnet would be made with D.C power, copper thick wire with 100 coils. I found that copper wire was the best conductor of all. For example, aluminum thick wire with 100 winds on A.C power picked up 123 iron filling out of 500 while copper thick wire with 100 coils on A.C power picked up 333 out of 500. l, the thicker the wire the more iron it picks up. More coils also make the electromagnet stronger. D.C Current is much stronger than A.C current. All the ones on A.C current picked up less iron than the ones on D.C current. If you compare copper thick wire with 25, 0, 75, 100 coils on A.C current, they will all be lower than the exact same thing from D.C current. There are 500 iron fillings in total. These are how many they picked up out of 500
Copper Thick Wire
A.C D.C
25 87 130
50 167 250
75 253 380
100 333 500
As you can see, by comparing the strongest types of wire on different currents, the D.C current is better for building an electromagnet.
The three wire I tested was aluminum, copper, and string. Aluminum conducted a good amount of power but the copper conducted more. The one that conducted the least was string which didn't conduct anything. String has no power in it and it can't conduct electricity. Aluminum and copper are conductor (especially copper) and string is an insulator. The best type of wire to use for building an electromagnet out of the three I tested is first copper, then second is aluminum, then last (and worst) is string. Remember to never use an insulator for a electromagnet or circut.
