diameter and directed outward perpendicular to the plane of the figure. Consider that the field is increasing at a rate of 21.4 V/m · s.
(a) What is the direction of the magnetic field at the point P, r = 13.5 cm from the center of the circle?
(b) What is the magnitude of the magnetic field at the point P, r = 13.5 cm from the center of the circle?
