Magnetic Reconnection

9 Dec 2018

At Tall Bloke's talk shop 'Old Brew' (which sounds like a winter warmer such as Sadler's Peaky Blinder) has a post on magnetic reconnection - see ... magnetic reconnection in space - experiment and satellite sightings. A magnetic field is more of a trajectory than an actual entity in spite of being discussed as if it actually exists. They are found in space just as they are found in bar magnets (see ) ...

   ... new research shows up similarities between laboratory records and observations of the four satellites of the Magnetosphere Multiscale Mission which studies magnetic reconnection in space. The four satellites hope to record the breaking and explosive reconnection of magnetic field lines in plasma throughout the universe - an ambitious project. So far they have found striking similarities with experiments at the Princeton Plasma Physics Laboratory. The studies are complimentary (but see also ).

JB comments by saying, the paper (in Nature Communications) sounds to me like they're still very much wide of understanding what is going on with charge flow and how it produces magnetic field gradients.
