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