the equations in the document you sent are for magnetic flux density inside the electormagnet. In the drawing you sent, I assume the wire is supposed to go through air, which has high magnetic flux resistance. With 5.7 mT in the core there will probably be negligent magnetic flux going through the wire in the air gap. I managed to create a 600 mT field in a 2.5 cm air gap at DC, but at 50 Hz AC I cannot get as high, it vibrates too much. I managed to do it with a silicon steel C-core, with 4 coils with 860 turns of wire connected in parallel, and about 3A. The C-C core pair has two legs, and when I made the air gap by putting the cores 2.5 cm apart, I filled one of the legs with ferromagnetic material to lower the magnetic flux resistance. If I manage to hold the magnetic cores in place somehow, I can try to put a wire through and do a measurement. But in general, if the air gap between electromagnets is half of the diameter (or the smaller of a rectangular-shaped magnetic core), the magnetic field in the air gap should be homogenous.
I already made a simulation of a bunch of 100 wires going through 7 pairs of electromagnets and the results were not spectacular. It is true though that I made the magnets long, bar-like and they were facing the wire with the smallest face, orienting them lengthwise like in your picture could be worth trying.
The air gap should be as small as possible if the diameter of the wire is e.g. 1 mm then the gap can be 1 mm just so you can fit the wires.
