    Magnets Poles
AI Thread Summary
Magnets cannot have the same poles at both ends; they always have a north and a south pole. A theoretical scenario exists where a bar magnet could have one pole in the middle and opposite poles at each end, but this does not create identical poles. The concept of magnetic monopoles, which would consist of a single magnetic pole, is possible in theory but has not been observed in practice. The discussion highlights the fundamental nature of magnetism and the current understanding of magnetic poles. Overall, magnets inherently possess distinct poles, and the search for monopoles remains an open scientific question.

Is it possible for a magnet to have same poles? i saw a question in which the compass points the same way in both ends.

You could in principle have a bar which is magnetised with one pole in the middle and the opposite pole to that at each end. E.g., glue the N poles of two magnets together.
As far as is known, a monopole is also possible, but none has ever been found.

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...
