Two parallel metal rails are placed a distance d apart...?
A metal bar is free to slide along these rails. If the bar moves along the rails with constant velocity v in the presence of a vertical magnetic field B, show using faraday's law in integral form that the magnitude of the voltage V induced between the rails is given by
V=Bvd

Faraday's Law
V ( induced voltage ) = dø / dt
ø = magnetic flux
dø = change in flux
dt = change in time
flux = B . A ( magnetic field strength . area )
Area mapped by moving bar = distance moved ( L ) . separation of rails ( d)
L ( distance moved) = v ( velocity) . dt
flux = B . v . dt . d
V = B .v . dt . d / dt = Bvd
