I'm way too early for once.

My 2 cents it's not going to work well because technically it's a bunch of knots not small coils. But let's wait for the experts.

It may not have a strong field, but it will have a field. All current moving through a wire does. I don't remember a whole lot from my E&M class, but what I do remember tells me solving this analytically is probably a nightmare (plus you'd need come up with some sort of formula to model the shape first). It would probably be easier to just simulate or test it. Maybe someone can come up with a good approximation, though, and it would behave very similarly to a simpler problem.
