...which starts a chain recation
No doubt propagated by errant spiraling vortices of magnetic flucks.
Actually that last post was one of the more coherent...
Hill and his team, working at the University of Nottingham in England, used a powerful superconducting magnet to produce a magnetic field of approximately 16 Tesla, nearly 350,000 times stronger than the strength of the Earth’s field. Operating at ultralow temperatures, superconductors offer no electrical resistance and, key to this experiment, they expel magnetic fields, which means they repel magnets. This repulsion can be stronger than the force of gravity, which leads to levitation.
The magnet created what’s known as a diamagnetic force, which can be large enough to balance the force of gravity, lifting the Drosophila melanogaster flies and suspending them midair. Diamagnetic materials, such as water, are pushed away by magnetic fields, so a powerful magnetic field can hold up small organisms like flies and frogs because they’re mostly made up of water.

Galactic magnetism may influence star birth
Given how much astronomers know about the cosmos, it might be surprising to learn how little they know about a basic process like star formation. A Nature paper published online November 16 makes some headway into how it works, suggesting that the host galaxy's magnetic fields play a significant role.
In particular, the authors studied one of the Milky Way's neighbors, the Pinwheel Galaxy (M33). Its nearly perfect face-on orientation provides an ideal target to watch the formation of molecular clouds, which act as stellar factories. The paper reports that six such clouds have magnetic fields in alignment with the Pinwheel's spiral arms, making it likely that the galaxy's overall magnetism works to anchor the clouds, affecting their distribution and the efficiency of star formation.
This finding is in contrast to other theories of cloud formation, which suggest that a cloud's internal turbulence and motion would be enough to overpower the galactic magnetic field. --Bill Andrews; Astronomy Magazine; March 2012.
Charge is generated in circuit, magnetic induction reverberates, current flows…
“ “"Its magnetic field [of Sun] is at less than half strength compared to the minimum of 22 years ago." Well, that doesn't make any sense. You can't compare one minimum to another. They must mean it is at half strength compared to some maximum. But it doesn't matter, since the magnetism won't tell us anything here anyway. The charge field we are passing through may be less magnetic than normal, but still have the same charge density. Magnetism just tells us how the [photons] are spinning, not how many of them there are.”
Update: Geomagnetic activity intensified even more on Feb. 15th when the interplanetary magnetic field (IMF) near Earth tilted south, opening a crack in Earth's magnetic field. Solar wind poured in and fueled a G1-class geomagnetic storm, now subsiding.
