Magnetic moment of a loop formed by a revolving electron

AI Thread Summary
The discussion centers on the behavior of an electron moving in a magnetic field, specifically its magnetic moment and potential energy. When an electron moves from top to bottom on a screen with an outward magnetic field, it revolves anti-clockwise, indicating a clockwise current flow. The magnetic moment is described as opposite to the magnetic field lines, leading to a state of unstable equilibrium with maximum potential energy. The participants express confusion about how a system can achieve a maximum energy configuration under these conditions. Clarification is sought on the relationship between the velocity vector of the charged particle and the magnetic flux density, particularly regarding the absence of magnetic force when they are in opposite directions.

Consider a situation.

If an electron is moving on your computer screen from top to bottom and the magnetic field is acting outwards towards your face, the electron revolves in anti-clockwise direction..

So we can say that the current is flowing in clockwise direction.
Magnetic moment when visualized comes in direction opposite to magnetic field lines.. which is the condition for unstable equilibrium.
So, potential energy = maximum using the formula P.E. = - \vec{m} . \vec{B}

How is this possible? How can a system arrange itself to a maximum energy configuration??

Velocity vector v of q charged particle and the magnetic flux density B are in opposite direction on a line. qvXB=0. No magnetic force apply to revolve particle.

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...
