Accleration and Magnetic fields?

Eelbot

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...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.
