Magnetic field inside diametrically magnetized ring magnet

AI Thread Summary
The discussion focuses on finding the correct formula to calculate the magnetic field strength within the inner diameter of a diametrically magnetized ring magnet. A user references a previous thread related to axially magnetized ring magnets, suggesting it might provide useful insights, although it may not directly apply to diametrically magnetized cases. There is a clear distinction between the two types of magnetization, prompting the need for a specific example for diametrically magnetized magnets. The conversation emphasizes the importance of accurate calculations for different magnetization orientations. Overall, the quest for precise formulas for diametrically magnetized ring magnets remains a key concern.

Could anyone point me to the proper formula to calculate the magnetic field strength in the gap/hole(ID) of a diametrically magnatized ring magnet.

Thank you. That is a good example for an axial magnatised ring magnet. It may calculate the same but that is why I was looking for a diametrically magnatized example

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.
