An electric field is restricted to a circular area of diameter d = 10.9 cm as shown in the figure. At the instant shown, the field direction is out of the page, its magnitude is 300 V/m, and its magnitude is increasing at a rate of 18.0 V/(m · s). A)What is the direction of the magnetic field at the point P, r = 16.6 cm from the center of the circle? B)What is the magnitude of the magnetic field (in T) at the point P, r = 16.6 cm from the center of the circle? C) As before, at the moment shown in the figure, the electric field within the circle has a magnitude of 300 V/m and is increasing at a rate of 18.0 V/(m · s). In addition, suppose that the radius of the circular area of the electric field increases at a rate of 1.00 cm/s. What would the magnitude of the magnetic field be at point P at this moment (in T)?
