Your wording seems incomplete to comment accurately on. Would you mind saying what you just said, but a different way?

It may appear that way, but that's not the case. The only difference is where the jumpers are located, the rear of the speaker or the rear of the receiver. That might have some effect if electron waves didn't pass through insulated wire at approximately 130,000 miles per second, but since they do it doesn't.
Do you mean to say "bi-amp?" My speakers are bi-amped, so the speakers have no cross-overs. The amps do all of the work.
Presuming you are talking about bi-wire to passive crossovers at the speaker end... yes, you will be measuring different current draw going to the different sides/drivers. Thus the different EMF on either peer of cables.
.
Yes there have been a few mathematical demonstrations of this phenomena. But at the end of the day most will agree it makes no audible difference.

+1, you can mathematically predict it, and you can measure it. It's the main argument made by cable crooks to justify why you should pay them for two sets of cables. But you can't hear it. If you could it would show up on a measured speaker response and THD chart. That crucial bit of data never makes its way into cable crook advertising copy.
Electromagnetic fields are created by current flow.
Electric field is created by voltage.
EMF = current flow.
Probably adding nothing, the same thing happens between high and low pass sections of the crossover, whether it happens in 20 foot wires from the amp, or in the two inch jumper between the two sections on the back of the speaker or in the three inch wires from the speaker input to the two crossover sections, for speakers without biwire/biamp capability. the amp "sees" (or feels or smells or tastes, or however you want to imagine it) the exact same overall impedance and its summed output is exactly the same (less the tiny but possibly measurable difference from changes in wire impedance) AIUI, IMO, AFAIK, and any other disclaimer you want to imagine. Point is the real electrical difference is close enough to zero to be ignored. Otherwise folks would yammer about how the jumpered mono input isn't as clean or accurate or some other adjective as a real mono input with hard wiring into the two sections of the crossover would be. But they don't. because, I suspect, there's no money in it.
Which is why I like to passive bi-amp as well. Keeps the different currents/drivers on their own individual amp channels.
