A loop of wire is at the edge of a region of space containing auniform magnetic field B. The plane of the loop isperpendicular to the magnetic field. Now the loop is pulled out ofthis region in such a way that the area A of the coil inside the magnetic field region isdecreasing at the constant rate c. That is, dA -c, with dt c> 0.
