These new iron-nitride magnets are stronger, cleaner to make, and made from domestic iron-salt waste and nitrogen. Science is slowly chipping away at the various environmental and geopolitical ...

The magnetic fields that formed in the very early stages of the Universe, may have been billions of times weaker than a small fridge magnet, with strengths comparable to magnetism generated by neurons ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the ...
