As it stands now, I've found a calculator that optimizes the number of turns for the space given and wire gauge. It then uses that information and your input voltage to come up with the current, power, and it will estimate the "gauss at center". Now this is in the case of a simple electromagnet...
If I were to build a solenoid for the sake of making an electromagnet with a core shaped like the one below, would it create the desired effect?
CRUDE! :-p Cross-sectional view of my idea.
What I'm asking is, would the inner edges of that gap (the sides closest to the center) be one...
