The Role of Magnetic Fields in AGN Activity and Feedback

, 2018
Active galactic nuclei (AGNs), the luminous, compact core regions of galaxies where accretion occurs onto supermassive black holes, can dramatically influence their entire host galaxy evolution by a process referred to as AGN feedback. Energy feedback to

Magnetic fields around evolved stars [Elektronisk resurs]

, 2018
There has long been evidence of magnetic fields in the extended envelopes of asymptotic giant branch (AGB) and red supergiant (RSG) stars. These stars are important contributors to the enrichment of the interstellar medium by dust and heavy elements ...

Demo 19-09 Magnetic Fields Around Currents

, 2001
The magnetic field around various geometries of conductors can be observed using iron filings. While the current is running through the wire, iron filings are sprinkled onto a plastic sheet through which the wire runs, and the plate is gently tapped ...
