Why is there a correlation between gravitational and magnetic fields?

AI Thread Summary
Gravitational and magnetic fields both exhibit an inverse-square law, decreasing in strength with the square of the distance from their source. Despite being fundamentally different forces, the discussion suggests that their correlation may stem from shared mathematical properties, particularly the concept of divergence. The idea of magnetic monopoles is introduced as a hypothetical means to achieve a similar inverse-square behavior for magnetic fields, though they remain unobserved. The conversation references established theories like the Standard Model and the Theory of Everything to explore these connections. Understanding these relationships could deepen insights into fundamental physics.

A gravitational field and a magnetic field both decrease in strength at the distance squared. They are two totally different forces so why the correlation?

no its not that complex -- Invalid ID ;)

read all about it here on wiki
http://en.wikipedia.org/wiki/Inverse-square_law

its also the same for an E-M wave ( light, radiowave )

So is it fair to say that divergence is what they have in common?
 
The vanishing divergence without sources in the common reason for both inverse square laws, indeed.
To have a magnetic field decreasing as inverse square law, you would need (unobserved) magnetic monopoles, however. It is easier with electric fields.

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.
