    Dipoles Electrons
AI Thread Summary
Electrons are not dipoles; they are single point charges with an intrinsic magnetic dipole moment due to their spin. The confusion arises from the misconception that electrons can be viewed as having two opposite charges separated by a distance, which is incorrect. Instead, the magnetic dipole moment is a fundamental property of the electron itself. This property is related to concepts like gyromagnetic ratios and g-factors. Understanding these distinctions clarifies why electrons do not attract each other as dipoles would.

If the electrons are small tiny dipoles, how do then they refuse them selfs? Thanks. I appreciate your help.

I'm not sure I understand your terminology. Electrons are not dipoles by themselves, unless you are referring to something other than an electric dipole. Could you please clarify, and provide a web pointer to what you are asking about?

I think what you are asking is something like, "If I imagine that the electron's dipole moment is produced by two opposite charges some small distance apart then what holds the two charges at that fixed small distance apart?"

Well, the electron's dipole moment is *not* produced by two small charges a fixed small distance apart. It is an intrinsic property of the electron itself proportional to its spin.

I think he means that if the electrons are dipoles (one positive end and one negative end), then why doesn't the positive end of the dipole attract to the negative end of another electron.

Your assumption is wrong. Electrons are not dipoles.
 
Ok, thank you very much.
 
electronic confusion

The electron is a single point charge, and so does not have an electric dipole moment. However it does have a magnetic dipole moment - that is it does act like a little magnet in addition to its charge. This is related to its spin. Look up gyromagnetic ratios and g- factors.
 
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...
