Blackett effect and Earth's magnetic field

AI Thread Summary
Blackett's effect, which suggests that electrically neutral rotating masses can produce magnetic fields, is widely disputed, with claims that it does not exist. Critics argue that the only information available will reinforce this non-existence. However, some acknowledge that neutral rotating masses can generate minute magnetic fields due to factors like thermal current fluctuations and centrifugal forces. The focus of the discussion also includes interest in the derivation of Blackett's formula, despite skepticism about the phenomenon itself. Overall, the conversation highlights the controversy surrounding Blackett's effect and its implications in physics.

I'm looking for information on Blackett's effect in general and the derivation of his fomula in particular.

www.stardrive.org/Jack/blackett1.pdf[/URL][/QUOTE]Despite what this paper suggests, Blackett's effect does not exist. Electrically neutral rotating masses do not produce magnetic fields. So the only "information" you will find on it will say that it does not exist. You may find misinformation, like this paper, that will suggest otherwise.

Whether this phenomenon really exist is of little importance to me.
What I'm interested in is how he got to that formula.
Btw, neutral rotating masses do produce minute magnetic field due to small effects like thermal current fluctuations, centrifugal forces, gravity etc.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
