Q25: A 2.00-m length of wire is held in an east–west direc- tion and moves horizontally to the north with a speed of 0.500 m/s. The Earth’s magnetic field in this region is of magnitude 50.0 mT and is directed northward and 53.08 below the horizontal.
(a) Calculate the magni- tude of the induced emf between the ends of the wire and
(b) determine which end is positive.
