Hi!
This forum has been extremely helpful to me in the past, and I am hoping I can get a little more benefit from all of your collective experiences.
I have recently become interested in electromagnetic fields generated by electromagnets.
I have not, however, had any luck at all figuring out how to calculate the strength of a field produced by a given electromagnet.
For example:
If I have a 1/16 of an inch iron rod, with a single layer of 36 gauge wire wrapped around it (the number of coils will vary with length of course) and I am running (v) volts through it with (I) amps, how strong will the field be at (x) inches from the coil? How do I do this with metric?
And once I have the answer, I am sure the units will be of no use to me, so how do I use that to work out how much actual weight the thing can move of different materials at different distances?
And does the shape of the object being moved matter?
What if Im using a magnet as the "object being moved"?
What shape will the field be?
This is literally so far beyond me to work out on my own that I dont even know where to begin. I tried the usual googleing, but everything I came up with seems to assume that I already have an electrical engineering degree.
Even a simplified kids version that just gave me a rough idea would be great!
Thanks so much guys,
-Liam.

What happens when I change the diameter of the wire or the core? What about different insulators around the wire? What happens if I change the pattern of wraps, or change direction at the end of the core and come back? Does is help or hurt?
Thanks!
