At the ends of the wire, v is perpendicular to B - thus, there is a magnetic force acting on the charges there. However, the wire itself is parallel to B, and as a result, the charges have no space to move - there is no current.

In this case, a wire segment is moving through a magnetic field. The equation that applies to this case is: emf = vBL, which holds only when v (velocity), B (magnetic field), and L (length) are mutually perpendicular. Looking at the diagram, one can see that the three values are not mutually...

The wire has charged particles, right? If the wire falls, then the charged particles (which are confined to the wire) are also falling. If charged particles move in a direction perpendicular to the magnetic field, a magnetic force acts on them. In this case, the magnetic field (at the ends of...

That's what I initially thought. There is a magnetic force acting on the charged particles at the ends of the wire, but these charges have nowhere to go and thus, there is no current. However, I was wondering if the magnetic forces acting on the ends of the wire could exert torque on the wire...

Suppose a single wire (in a horizontal position) falls toward a pole of a magnet. Does the wire slow down? A diagram is attached.
