Polarized light observations from ALMA reveal the magnetic structures and galactic outflows in Arp 220, the nearest ultraluminous infrared galaxy to Earth, providing detailed field maps.

Importantly, this effect is even in place for relatively weak magnetic fields, so it could be utilized for probing magnetic fields that are even weaker than Earth, though the orientation of the field ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...
