A parallel plate capacitor of area $\displaystyle 60 \mathrm{~cm}^2$ and separation $\displaystyle 3$ mm is charged initially to $\displaystyle 90 \mu \mathrm{C}$. If the medium between the plate gets slightly conducting and the plate loses the charge initially at the rate of $\displaystyle 2.5 \times 10^{-8} \mathrm{C} / \mathrm{s}$, then what is the magnetic field between the plates ?
