Magnetic sphere and induced current

AI Thread Summary
A magnetic sphere traveling down a track of conducting wires with current flowing through them will interact with the magnetic fields generated by both the sphere and the wires. The interaction could potentially induce a current in the wires, possibly in the opposite direction, depending on various factors. Key elements influencing the outcome include the strength of the magnet, the type of magnetic field (dipole, quadrupole, etc.), and physical parameters like mass, friction, spacing, initial velocity, and angular momentum. The complexity of the scenario suggests that detailed analysis or experimentation would be necessary to predict the exact behavior. Understanding these interactions is crucial for applications in electromagnetism and related fields.

Hey guys, I have a scenario where I can't figure out what would happen.

If I have a magnetic sphere traveling down a track made of two conducting wires (each with current flowing through them)... what would happen?

I'm not sure how the magnetic field of the wire and the magnetic field of the sphere would interact... and could a current be induced in the wires in the opposite direction?
 
Physics news on Phys.org
The current carrying wires would have a magnetic field which would interact with the magnetic field of the sphere. The details of the resultant motion would depend on all sorts of things like the strength of the magnet and the current, whether the magnet were a dipole, or a quadrupole, or some higher-order multipole, the mass, friction, spacing, initial velocity, initial angular momentum, etc.

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...
