help with an electromagnet

[AnotherNewbie]

HI,

I want to build an electromagnet, but I don't know how to determine the parts.

Can someone help me with the construction details?

I have a 2000 Gauss, 1 inch round permanent magnet. I want to duplicate the 2000 Gauss strength in an electromagnet with a 3/4 inch diameter, 2 inch length solid metal core.

The questions are:

What kind of metal should the core be? (I want minimum remanence)
What kind of wire should I use?
What gauge winding wire should I use?
How many turns do I need to make?
What other information do I need?
How do I find out how many watts are needed to make it work?

Have a good one all.

Thanks

Who are you and why did you post this?

I posted it because I don't know the specs on how to make an electromagnet like I want. This seemed like a place where I could get this information. Am I wrong?

I am someone messing around with magnets and electromagnets, like a lot of others. Are you asking me for my name, address and phone number?

If you want to make a strong electromagnet check this topic:

Thanks Jesus,

I read every post in that thread, unfortunately I still don't know what gauge wire to use or the number of turns. I do have a better grasp about materials, but again there was no conclusion on what was best.

Little by little I am learning what I need to know.

Thanks for the help.
