I don't understand the conflict with using multiple MOTs as
electromagnets. Every second electromagnet could be driven
with opposite polarity so that no repulsion occurs between
them, yes?

Well, the MOT electromagnets have both poles in the same plane, so you
wouldn't have to alternate. Like you would with magnets with poles on
the opposite ends of a bar or cylinder. Bob

There's 2 ways to arrange MOT electromagnets (MOTEs) and it occurs to me
that I'm not sure that we're thinking of the same way.

If the top surface of a MOTE has poles N-S-N, then I'm thinking that
multiple MOTEs would be arranged:

N N N
| | |
S S S
| | |
N N N ...

not

N-S-N N-S-N N-S-N ... (or N-S-N S-N-S N-S-N if you prefer)

The first way puts the front pole very close to the bend axis, the
second one puts it about an inch more away (the thickness of the winding.

So, by extension:

N N N S S S
| | | | | |
S S S N N N
| | | | | |
N N N S S S ...

Yes?
