Consider the process of charging a parallel plate capacitor with circular plates of radius R=5 cm separated by a distance d=0.2 cm. At some time t1, the capacitor is being charged with a current I=0.075 A.

Consider a point P on the plane which is equally distant from the two plates and is a distance r=0.0505 m away from the axis of the capacitor. (a) Calculate the magnitude of the magnetic field (in Tesla) at a point P at time t1 during the charge of the capacitor.

(b) Calculate the magnitude of the magnetic field (in Tesla) at a point P after the capacitor is fully charged.
