Magnetic fields can send particles to infinity....[and beyond!]

So now all we’ve to to do is figure out how to reduce Obama to a particle.

We need an "Obama particle". It is always negative. It takes its energy from other particles. It leaves a huge negative balance all while doing nothing itself.

I can see no meaning in the phrase “Sending particles to infinity”.

Try wrestling with "beyond" infinity.

One of the conditions is that the field is generated by current loops situated on the same plane

The branes in Spain stay mainly in the plane...

They must do their graduate study at Compluperfectense University....

[noinfringers3]

Are we being confused with infinity and existence?

>Is the universe finite or infinite?

The one we live in is likely still expanding.

Beyond this universe there are likely infinite big bangs creating infinite universes. I see no reason to draw a line
in space and claim it as the end of everything.

Humans can’t define infinitely big or small and just settle for shoes that fit comfortably.

However, the "something else" goes beyond the established limits.

Doesn't it always!

How fast?

Because if it’s traveling at the speed of sound, it’s really unremarkable.

Crap, I thought this read the way it did because it was Google-translated from Spanish, but then I went to the site and found it was in English to begin with:

Here is the intro from the paper:

1. Introduction. The late Prof. Ulam, cf. [1], repeatedly stressed the importance of the study of the magnetic field B created by closed (cyclic or periodic) wires, as a source of mathematical problems: the presence of knotted streamlines of B, ergodic streamlines in open sets of R3, applications in plasma physics and biology, [2]. Recently, [3], the unreachability of the wires (the sources of B) when a charged particle moves in R3 under the presence of B was proved either for a finite number of parallel wires (that is, for a finite number of parallel straight lines) or for a finite number of circular wires, lying on parallel planes πi, its centers lying on a straight line L orthogonal to the planes πi. We study in this paper the escape to infinity of electric charges under the presence of the magnetic field B created by closed wires traversed by electrical intensities Ii. It is assumed that the electric charges interact with B via the Lorentz equation, x¨ = x˙ ∧ B. (1.1) For electric charges, interacting with the electric field E created by pointlike charges, escape to infinity was studied in [4]–[5]. The reader should have a look at references [6] and [7], where Matsuno and Goriely and Hyde studied the escape of Rn vector fields via Painlev´e analysis. The references in [8]–[22] are also useful concerning the escape for polynomial vector fields.

Concerning escape to infinity in the presence of magnetic fields B(x) created or not created by a finite number of cyclic wires, the authors are not aware of previous references studying this problem.
