The magnetic field B at all points within the colored circle of the figure (Figure 1)has an initial magnitude of 0.700 T. (The circle could represent approximately the space inside a long, thin solenoid.) The magnetic field is directed into the plane of the diagram and is decreasing at the rate of 0.0300 T/s.
