If you are asking about the bulbous shape of the magnetic bottle, it is shaped by the fact that at each perpendicular cross section outside the magnet 1, the trains of elementary strings repulse each other and are on their way apart and back to the other end of magnet 1. However, attractive forces from the proximity of magnet 2 takes over and pulls the strings back in toward magnet 2.Sparky wrote: If these fields are constructed of aligned particles, what keeps them separated?
n this paper, we analytically and numerically show that a transverse DW (TW) can be moved by an OOP [Out of Plane] field pulse. The direction of the TW displacement depends on the field direction and the chirality of the TW [Transverse Domain Wall].
http://www.nature.com/ncomms/2014/14032 ... s4429.htmlsynchronous current-induced domain wall motion was studied, but the required high-current densities prevent widespread use in devices.
Here we demonstrate a radically different approach: we use out-of-plane magnetic field pulses to move in-plane domains, thus combining field-induced magnetization dynamics with the ability to move neighbouring domain walls in the same direction. Micromagnetic simulations suggest that synchronous permanent displacement of multiple magnetic walls can be achieved by using transverse domain walls with identical chirality combined with regular pinning sites and an asymmetric pulse.
By performing scanning transmission X-ray microscopy, we are able to experimentally demonstrate in-plane magnetized domain wall motion due to out-of-plane magnetic field pulses.

Our Galaxy's Magnetic Field is revealed in a new image from ESA's Planck satellite. This image was compiled from the first all-sky observations of 'polarised' light emitted by interstellar dust in the Milky Way.
… the Planck image shows that there is large-scale organisation in some parts of the Galactic magnetic field.
The dark band running horizontally across the centre corresponds to the Galactic Plane. Here, the polarisation reveals a regular pattern on large angular scales, which is due to the magnetic field lines being predominantly parallel to the plane of the Milky Way.
The Atomic Picture of Magnetism
Scientists from the Max Planck Institute for Solid State Research in Stuttgart and Augsburg are making their contribution to a more detailed understanding of how iron-based superconductors work and the role played by magnetism. They are the first to have imaged the magnetic structure of a so-called strongly correlated electron system, here of iron telluride, on an atomic scale ("Real-space imaging of the atomic-scale magnetic structure of Fe1+yTe ").
.“A key question which many research groups are now posing is the one about the relationship between magnetic and superconducting properties of these materials,” says Peter Wahl from the Max Planck Institute for Solid State Research and University of St Andrews. “Can both effects occur at one and the same location? Or are they mutually exclusive?” Physicists think it is possible that the magnetic properties of the materials could even be the cause of their superconductivity
The Stuttgart-based Max Planck researchers have now made use of a so-called spin-polarised scanning tunneling microscope, which can image the orientation of the magnetic moments of individual atoms. The method is not new, but has so far mostly been applied to metal surfaces and nanostructures. What was not clear until now was…
Narrow longitudinal stripes, which result from the anti-ferromagnetic order in the iron telluride, can be recognised in the image taken by the scanning tunnelling microscope. Within the stripes, all magnetic moments have the same orientation; on the adjacent stripes, it is in the opposite direction.
...
The Research Group lead by Peter Wahl also determined that the magnetic order becomes more complex when the proportion of iron atoms is higher: the longitudinal stripes partially dissolve, and are overlaid by transverse stripes.
The results were just published in Science magazineQuantum-mechanical monopoles discovered
" In this nonmagnetic state, a structure was created in the field describing the gas, resembling the magnetic monopole particle as described in grand unified theories of particle physics.
Sure, and Topological Defects called 'sunspots' will be discovered to be "monopoles" .The discovery of a magnetic monopole particle is still in the future. This new result establishes that the structure of a quantum mechanical monopole does appear in nature, and therefore it further supports the possibility that magnetic monopoles exist.

From: http://milesmathis.com/per4.pdfHaving all those protons on the axis also helps us explain the magnetic qualities of Iron (and other elements built like this). Magnetic strength is now given to domain alignment, but that has never been
connected to any real mechanics. Here we can see that magnetic strength has more to do with charge
conduction in both directions along the axis

The W boson then decays into the electron and anti-neutrino.
The W boson allows charge to move from particle to particle, aka, the weak force.
