A 2.00-m length of wire is held in an east west direction and moves horizontally to the north with a speed of 15.0 m/s. The vertical component of Earth's magnetic field in this region is 40.0 T directed downward. Calculate the induced emf between the ends of the wire and determine which end is positive.
