  • A magnetic line broke into my house and stole my dog.

  • Good call. Science should give up on the whole "expanding the horizons of human knowledge" thing and just make videos of explosions and animals falling over while mating.

  • Yes, charged particles(tiny bits of matter) are being created along the Sun's magnetic reconnection. This explains the age of Saturn's rings and much more.

  • OH DAMN2009?

  • Nice

  • other than causes of life and crazy colored lights in the sky.. has anyone ever thought that this energy is used as a means of speeding up space travel... interplanetary sling shots and the gravitational pull of the sun...

  • Yep, electromagnetic fields aren't a medium, they are vector fields that don't need a medium to exist. The lines only depict the direction of the field.

  • Not to smash your well established theory, but magnetic field lines are very very real. A simple bar magnet and iron fillings will show this to you.

    As for magnetic reconnection, it occurs when two distinct dipoles "break" and then "reconnect" with eachother. This releases a large amount of energy stored in the magnetic field. The actual reconnection doesn't mean the individual lines are reconnecting but that the south of one is connecting to the north of the other and vice versa.

  • nt true

  • RUBBISH magnetic field lines DO NOT RECONNECT. Lines are visualisation aids used to depict a continuous medium. Whoever said this needs to do electrical 101.

    Come on this is supposed to be New Scientist, not New Fiction regurgitation. Apply some critical thought to your reporting.

  • Its funny they mention that the sun has something to do with the Aurora Borealis, because it happens at both poles, whichever pole is facing the sun more, Because of our wabble it changes slightly from the north to the south, anyways the radiation the sun sends is what causes this, hence the two lines reconnection, thats because of the radiation flowing through the planet, because its alittle more hollow then you think. And radiation comes out of both poles in broken down particles in lightform
