Which of the loops would feel a magnetic force directed to the right?

AI Thread Summary
The discussion centers on determining which rectangular wire loops experience a magnetic force directed to the right in a uniform magnetic field that exits the page. Initial attempts using the right-hand rule suggested that none of the loops would feel such a force, but this conclusion was challenged. The concept of induced force opposing changes in magnetic flux through the loops was introduced as a potential factor in the analysis. Participants are exploring various solution choices to identify the correct loops that would experience the force. The conversation emphasizes the need for a deeper understanding of magnetic forces and flux changes in relation to the loops' movements.

Problem:

The figure shows a region of uniform magnetic field out of the page. Outside the region, the magnetic field is zero. Some rectangular wire loops move as indicated. Which of the loops would feel a magnetic force directed to the right?

Attempted Solution:

By right hand rule none of these had a magnetic force to the right.

NOPE. Not right. Not sure why its not right either.

Possible Solution Choices:

a) 1
b) 2
c) 3
d) 4
e) 1 and 2
f) 2 and 4
g) 3 and 4
h) none of them

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...
