An electric field is restricted to a circular area of diameter d = 10.6 cm as shown in the figure. Eout r P 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 18.6 V/(m·s). (a) What is the direction of the magnetic field at the point P, r = 16.4 cm from the center of the circle? ○ upwards downwards (b) What is the magnitude of the magnetic field (in T) at the point P, r = 16.4 cm from the center of the circle? T (c) What If? 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 18.6 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)? T
