I'm not taking this course for credit...

Hi! Is this a good text after Halliday?

I'm trying problem 7.7-

a metal bar of mass m slides frictionlessly on 2 conducting rails...

perhaps the current is I=integral J dot da, generated by the moving metal bar, velocity v (results in changing reference frame and B field which results in EMF driving current vertically up through the wire?) is the force diagram similar to 7.11?

I'm unclear on the geometry of the force digram?

thanks very much
