Part A A loop of wire is at the edge of a region of space containing a uniform magnetic field B. The plane of the loop is perpendicular to the magnetic field. Now the loop The induced emf in the loop is measured to be V. What is the magnitude B of the magnetic field that the loop was in? is pulled out of this region in such a way that the area A Express your answer in terms of some or all of the variables A, C, and V. of the coil inside the magnetic field region is decreasing at the constant rate c. That is, View Available Hint(s) dt d.A = - C. with c > 0. AEd B = Submit Part B For the case of a square loop of side length L being pulled out of the magnetic field with constant speed v. (see the figure), what is the rate of change of area c = - di ? (Figure 1) Express your answer in terms of L and v. View Available Hint(s) AEd ? CE Submit Provide Feedback
