That’s a neat idea! (Do they still say “neat”? 
) I can see some Hiders liking it. Until someone else detects its heat signature, anyhow. That’s a lot of physical resources to take advantage of!
You mention “it rotates around its own center of mass...” Have you figured out how fast that might have to be? (I have not the slightest idea how to determine what forces the resulting magnetic field, if any, would apply to the structure.)
It seems to me that it has to rotate fast enough that the net “gravity” on its exterior side, the outermost circumference of the doughnut, farthest from the center of mass, would be zero or negative. Otherwise, I’m guessing, it’d eventually crumple into a sphere. That’d result in a complicated shape for the apparent surface gravity, I think. I’m also assuming no transapient structural support like magmatter. I dunno if that’s a reasonable assumption, though.
Am I overlooking something?
