1. A coil has 180turns enclosing an area of 11.3 cm2 . In a physics laboratory experiment, the coil is rotated during the time interval 0.050 s from a position in which the plane of each turn is perpendicular to Earth's magnetic field to one in which the plane of each turn is parallel to the field. The magnitude of Earth's magnetic field at the lab location is 6.5010^?5 T .

What is the magnitude of the average emf induced in the entire coil? Express your answer in volts.

2. In the figure, a conducting rod of length L = 34.0 cm moves in a magnetic field B of magnitude 0.350 T directed into the plane of the figure. The rod moves with speed v = 4.00 m/s in the direction shown.
