2a. An electric generator utilizes the principle of magnetic induction to generate a DC current. To do this, a wire loop is rotated relative to a hard magnet so that the magnetic flux through the loop is constantly changing (see the diagram below). However, this process is slightly flawed to produce a constant DC current that always moves in the same direction. Explain why this is flawed.
