The area goes on increasing when the rod moves to the right which increases the flux into the plane of the screen, to oppose it according to Lenz's law an induced current flows in a direction which increases flux out of the plane of the screen, so the current flows in the counter clockwise direction.

The figure below shows a circuit consisting of a flashlight bulb, rated 3.0 V and 1.5 W. Assume the wires are ideal and have no resistance. The right wire of the circuit, the rod, is 12 cm long and is pulled at constant speed v through a perpendicular magnetic field of strength 0.25T (directed into the page). What current has to flow through the bulb for it to shine at the full brightness? What speed must the moving rod have...
