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=0.04 A.
Consider a point P on the plane which is equally distant from the two plates and is a distance r=0.0755 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.

Please help!

some1 plz help........!
