Well, I guess that's actually good news, because I was trying to find a project that would teach me some new stuff over the summer. Thanks for the heads up. I suppose I'm off to Google for a while.

Fair enough, thank you. If I get one of these DC supplies, is there some component I can put in the circuit so that the current through the primary solenoid varies?

Hey everyone! I've gotten some really good help over in the math section of physicsforums, and I was hoping to get some more of the same here in engineering. I've just finished my sophomore year in school, and I'm about to apply for the EE program at the university in spring. Anyway, I...

Yes, that was perfect. I used the surface z=g(x,y)=y^2-x, and got a normal vector from <-\frac{\partial g} {\partial x}, -\frac{\partial g}{\partial y}, 1> . Did my curl and dot product calculations to get \int\int_d <1,-2y,1>\cdot<-1,0,-x>dA=\int\int_d -x-1dA I converted to polar using...
