Classical approach to claculate magnetic force

AI Thread Summary
The discussion centers on the possibility of developing a generalized equation for calculating the magnetic force of interaction between magnets and ferromagnetic materials, such as iron. Participants express interest in understanding the dynamics of these interactions more comprehensively. The dyne is mentioned as a relevant unit of force in the context of magnetic calculations, highlighting the need for precise measurements. The conversation emphasizes the complexity of magnetic interactions and the potential for a unified approach to quantify them. Overall, the quest for a generalized equation remains a key focus of the discussion.

Would it be possible to have a generalised equation for magnetic force of interaction between magnet-magnet and magnet-ferromagnetic materials maybe iron.

Got this off the net a minute ago. Perhaps it will help?

The dyne (symbol "dyn", from Greek δύναμις (dynamis) meaning power, force) is a unit of force specified in the centimetre-gram-second (CGS) system of units, a predecessor of the modern SI. One dyne is equal to 10 µN (microNewtons), or to 10 nsn (nanosthenes) in the old metre-tonne-second system of units.

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...
