Magnets are always fun when used in science experiments and demonstrations. They are fairly inexpensive to buy and can be ...
Newly released images of the supermassive black hole at the heart of the galaxy M87 show that the plasma that swirls around ...
We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...
Schematic view of (top) currently used HAMR and (bottom) three-dimensional magnetic recording systems. In the three-dimensional magnetic recording system, the Curie temperature of each recording layer ...

The universe's first magnetic fields were 'comparable' to the human brain — and still linger within the 'cosmic web'
New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...
The early Universe hosted ultra-weak magnetic fields that still shaped cosmic structures. New simulations establish stricter limits on their strength. Magnetic fields that originated during the earlie ...
Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those ...
