Question

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 µT directed downward. Calculate the induced emf
between the ends of the wire and determine which end is
positive.
