Thanks for the input Marcus. As I said in my post, this was a hypothetical electromagnet. It's obvious that it's unworkable. Common sense and the claims of the Mag Lab show that. What I was looking for was a correction to the formula so that I could accurately design a high power electromagnet...

It's been many years since I studied this so I would appreciate some confirmation on the formula and its parts. The formula I was taught to calculate the Gauss of an electromagnet was: B=MNI/2R with: B = Magnetic flux in Gauss M= Magnetic permeability of core material N =...
