I'm struggling with physics problem, magnetic field inside a capacitor?

I'm stumped, asked my teacher, but his response didn't really help much. This is the question:

A 10-cm-diameter parallel plate capacitor has a 1.0 mm spacing. The electric field between the plates is increasing at the rate 1.0 x 10^6 V/m/s

Now, I know the formula for determining the magnetic field:

B = ((u0)/2pi)*(r/R^2)*(dQ/dt)
u0 is a greek symbol to represent 1.26*10^-6 T*m/A
r is the distance from center of capacitor
R is the radius of the capacitor
However, what I'm struggling with is the dQ/dt and the electric field increasing, how does those two relate? I'm lost :(
