Question

A 0.5-m length of wire is held in an east–to-west direction
and moves horizontally to the north with a speed of 2.0 m/s. In this region, the Earth’s magnetic field is of magnitude 60.0 μT and is directed
northward and 53.1 degrees below the horizontal. (a) Calculate the magnitude of the induced emf between the ends of the wire and (b) determine which end is positive.
