Magnetic diffusivity : significance?

AI Thread Summary
Magnetic diffusivity is a key concept in plasma physics, particularly within the context of the induction equation. It quantifies how magnetic fields interact with plasma, influencing the behavior of plasma as a fluid. Understanding diffusion in this context involves recognizing how magnetic fields can penetrate and affect the motion of charged particles in plasma. The discussion highlights a need for clearer explanations of these concepts, as many find them confusing. Overall, grasping magnetic diffusivity is essential for comprehending plasma dynamics and its implications in various scientific fields.

Magnetic diffusivity is a term that appears in the induction equation, when we deal with plasma fluids. It has units of meter squared per second.
I am unable to figure out what does the diffusion of plasma as a fluid implies.. It has something to do with magnetic field interacting with the plasma..

Someone please provide a detailed explanation..

what does diffusion means..? how can i physically understand it.. with a plasma..?

someone please reply...
 
nyone... please give some answer... ! :cry:
 
Plasma cosmology gibberish.
 
thanx for replying.. but that didn't help much.. :confused:
 
people should seriously consider studying plasmas for a change... :-/
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect...

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
