How do I make an Electromagnet? And a few questions about them and regular magnets?

   I’m looking to learn about electromagnets and magnets.
I looked up all those common videos on YouTube of course but It’s not the same as asking people who can tell me directly how to go about making one and things I can do with them.

   Here is what I know about electromagnets so far. I know that you wrap wire around a piece of iron neatly (the more times you wrap the stronger it is). Then you attach a battery to the ends of the two wires that are left and then you have a electromagnet. I also know that to much power is bad because it can heat up. I want to make some cool things with electromagnets. So here are my Questions:

Center Of The Electromagnets Questions
- What is the best thing to put in the center of a electromagnet?
- Is Iron the best and if so what is the best type of iron to use?
- If different materials will have different effects could you please list them?

Wire For The Electromagnets Questions
-What kind of wire works best?
-Will thinner or thicker wire wrapped more times around make it stronger?
-What is a good wire to iron ratio?

Power For the Electromagnet Questions
-Could I use a DC wall Plug instead of a battery?
-If I use a wall plug could I make a separate Positive and Negative electromagnet?

Few Random Questions
-What materials will that block electromagnets? Which works the best?
-What can you tell me about electromagnets that I didn’t ask?

Thanks for reading guys hope you guys can help. I check this constantly so feel  free to pour Info in here.

Center Of The Electromagnets Questions
- What is the best thing to put in the center of a electromagnet?
Something magnetic.
- Is Iron the best and if so what is the best type of iron to use?
Soft iron
- If different materials will have different effects could you please list them?
The more magnetic the material, the better.

Wire For The Electromagnets Questions
-What kind of wire works best?
Thick wire.
-Will thinner or thicker wire wrapped more times around make it stronger?
Thick wire wrapped more makes it stronger
-What is a good wire to iron ratio?
>pass<

Power For the Electromagnet Questions
-Could I use a DC wall Plug instead of a battery?
Yes, but some of them with poor rectification will have a lower effective strength as the current switches off 60 times a second.
-If I use a wall plug could I make a separate Positive and Negative electromagnet?
You don't get "positive" or "negative" electromagnets. Like any magnet, every electromagnet has a north and south pole.

Few Random Questions
-What materials will that block electromagnets? Which works the best?
Anything magnetic
-What can you tell me about electromagnets that I didn’t ask?
They can get hot - be careful.

I would just take any large nail or screw or bolt, they are most likely made of some kind of steel which contains iron, which in turn has magnetic properties and which in turn may be effected by forces of electricity - the whole attraction-repulsion thing wrap it a bunch of times with some insulated wire and connect the bare ends to the positive and negative terminals of a battery and not the wall socket because that is pretty dangerous and have it attract some other metal object when it is powered on. If you can attract something else magnetic like a striker rod for a bell, you can make the bell go ding ding ding repeatedly by pulsing the current or turning the power on and off quickly. But you hear that? Warning bells that we don't do anyone's homework questions around here. Gotta go. Bye.
