[E&M] Sliding Conductor & Magnetic Field

AI Thread Summary
The discussion focuses on the interaction between a sliding conductor and a magnetic field, specifically analyzing the Lorentz Force and the magnetic force on a current-carrying wire. The Lorentz Force (qvB) causes a charge separation in the conductor, resulting in current flow. The magnetic force (ILB) acts on the wire, with the direction determined by the right-hand rule, leading to a force directed west when the current flows north. The conversation raises a question about the orientation of the current when the conductor moves, suggesting that if the velocity is to the right, the current's effective direction may shift to north-east, affecting the magnetic force's orientation. This exploration highlights the complexities of analyzing forces in different reference frames.

Hello,

Please consider this diagram:

TnAlF.png


From the diagram, we can see there are two forces.

One: The Lorentz Force (qvB). Using the RHR, we can see that there is a force pushing north (up) to cause the separation of charges in the sliding conductor to establish the current in the loop.

Two: The Magnetic Force on a Current Carrying Wire (ILB). Orienting our index towards the direction of the current (north in the conductor) and the middle finger into the page, we can see that there is a resulting force pushing in the west direction (to the left).

Now these assumptions are generated if we are in the reference frames of the rails.

If the current is flowing north, and the velocity is oriented towards the right, would we consider that the direction of the current to be north-east? As a result, wouldn't the magnetic force be oriented slightly north-west?

Thanks!

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...
