Are Magnetic Poles and Currents Equivalent Theories in Creating Magnetic Fields?

AI Thread Summary
Magnetic fields are primarily created by electric currents, as stated in Griffiths' work, while the concept of magnetic poles is often used for mathematical convenience. Although magnetic monopoles are frequently referenced in equations, they do not exist in reality; only currents generate magnetic fields. Theories regarding magnetic poles and currents are considered equivalent in terms of the magnetic fields they produce, despite the absence of magnetic monopoles. There is no definitive proof that the theory of magnetic poles is incorrect; it remains a hypothesis used for simplification in physics. Ultimately, the primary source of magnetic fields is electric currents, not magnetic poles.

what creates magnetic fields, magnetic poles or currents? are those theories equivalent mathematically? i read in Griffiths currents are the sole source of magnetic fields but in another book it said those theories are equivalent. has it been proved the theory of magnetic poles is wrong/ or is it just still a hypothesis?

people often use magnetic monopoles in equations, just because it makes things easier. In reality, there are only currents, no magnetic monopoles. But they can cause approximately the same magnetic fields, which is why magnetic monopoles are sometimes used in equations.
 
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...
