4a. Suppose a 42–turn coil lies in the plane of the page in a uniform magnetic field that is directed into the page. The coil originally has an area of 0.290 m2. It is stretched to have no area in 0.100 s. What is the magnitude of the induced emf if the uniform magnetic field has a strength of 1.70 T? 4b. What is the direction of induced emf? A. CCW B. CW
