A magnetic field of 0.080 T is in
the y-direction. The velocity of wire
segment S has a magnitude of 78 m/s and
components of 18 m/s in
the x-direction, 24 m/s in
the y-direction, and 72 m/s in
the z-direction. The segment has
length 0.50 m and is parallel to
the z-axis as it moves.
What would the motional emf be if the wire segment was parallel
to the y-axis?
