Can magnetic poles have varying strengths?

AI Thread Summary
Magnetic poles cannot have varying strengths due to the absence of magnetic monopoles, meaning all magnetic field lines are closed. While it's possible to alter the overall field strength, this change must correspond with a variation in the size of the magnetic field. The concept of defining "strength of a pole" is complex and not straightforward. Therefore, both poles of a magnet inherently maintain equal strength. The discussion highlights the fundamental principles of magnetism and the limitations in manipulating magnetic pole strength.

I'm quite new here, but here's my question:

Is there a way to make one magnetic pole stronger than another?
 
Physics news on Phys.org
There are no magnetic monopoles (at least no were found yet), so all field lines are closed. In terms of classic magnets, this corresponds to "poles of equal strength" (note that it is not trivial to define "strength of a pole" at all). You can get a different field strength, but that has to correspond with a different size of that field, too.

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.
