Here we are. For a flat coil, which is the nearest kind of coil like the focus fusrion the magnetic field is B=μ*N*I/(2*r). Same figures again but N=1 gives

B=2*10(exp-7)*1/(2*1,0*10(exp-5))= 10 000 Tesla which still is a awful lot. It doesn’t matter how many turns the coil has. Either you take number of turns and current in each of them or all current and one lap, which I did, since sum of current is the only thing I know. I think that such kind of magnetic field, though it’s very strong is also very narrow. It will not change the direction of any ones compass.
