Accleration and Magnetic fields?

AI Thread Summary
A toroidal conductor generates a circular magnetic field, which influences charged particles within it. A charged object, like an electron, would experience a force due to the Lorentz force, causing it to move in a circular path if it enters the field with velocity. However, an uncharged object, such as a metal ball, would not be affected by the magnetic field and would remain stationary. The Lorentz force indicates that only moving charged particles feel a force in a magnetic field, as stationary charges do not experience any work. Therefore, movement is essential for the interaction between charged particles and magnetic fields.

I just have a question based on a toroidal conductor. I know that the magnetic field would run in a circle (http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/imgmag/tor.gif). I am wondering if that magnetic field would do anything. For example, if I dropped something charged into there, would it move in a circle? What about something uncharged, like a ball of metal? What would be the effect on an object in that magnetic field?

If you shot an electron in their with speed v it we feel a force.
What does the Lorentz force say about the direction. And If you just placed an electron in their it would not move, Magnetic fields can't do work, the electron has to be moving to feel the force.

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...
