Finding Magnetic Force?

  • #1
I have a problem where I'm given a conducting bar that slides to the right on 2 conducting rails.

The magnetic field is given, as well as the resistance, the length of the bar, and the speed that the bar is moving.

The magnetic force is what is wanted. Now I know 3 formulas

F= qv x B, F = IL x B, and the centripetal force, all forces that can be applied to magnetic force.

But I cannot figure out this problem for the life of me. Can anyone help?

You have to find the current in the bar from Faraday's law.
