A loop of wire is at the edge of a region of space containing a uniform magnetic field B⃗ . The plane of the loop is perpendicular to the magnetic field. Now the loop is pulled out of this region in such a way that the area A of the coil inside the magnetic field region is decreasing at the constant rate c. That is, dAdt=−c, with c>0.Part A
The induced emf in the loop is measuredto be V. What is the magnitude B of the magnetic field that the loop was in?
Part B
For the case of a square loop of sidelength L being pulled out of the magneticfield with constant speed v, what is the rate of change ofarea c = -\frac{da}{dt}?
