a)Suppose a 32-turn coil lies in the plane of the screen in a uniform magnetic field that is directed into the screen. The coil originally has an area of 0.66 m2. It is stretched to have no area in 0.42 s. What is the magnitude, in volts, of the average induced emf if the uniform magnetic field has a strength of 8.75 T? b) what is the direction of the induced current?
