Hey guys, I think I really just need some help with Google search terms here...
I am making a solenoid, or more specifically, the coil part. I need to find an online calculator or some equations to figure out the proper gauge and number of wraps to give me a given resistance and/or strength. I am sure they are out there but for the life of me, I can not seem to put together the proper set of Google search terms to get me to where I need to be. I have been googling for over an hour now finding nothing of any use.
Has anyone come across these types of calculations? --My only other option is to just go ahead and make a coil, measure it, and calculate from there --But that is going to be a waste of wire ($9 from friggin' Radio Shack) and I doubt the math will be perfectly linear.
Here is one I just used some
Here is one I just used some keywords from what you wrote and got this
Have you Bing!ed it? 
Have you Bing!ed it? C’mon show us some effort 
I just threw an handful of terms (diy electromagnet solenoid calculator) at goggle and among the things it spit back, this looked like it might be useful:

especially it was an excel sheet that might be handy: http://www.coolmagnetman.com/coildata.xls
Finally!!
Man, thanks guys!
I dunno what happened, my Google-foo just didnt happen this time, I guess. I suppose it happens to the best of us from time to time.
Thanks again.
I pulled this from one of my books.
its my go-to artical on electromagnets.
electromagnets.pdf
I hope it helps. And i hope i got the link correct.
ok fixed now

All I can say is wow… That PDF is awesome! I love that old Popular Science/Mechanics stuff. So much good info.
Thanks
–BTW, in the next few weeks or so, we gotta start talking about this year’s Maker.
