The magnetic field Bw is measured at a distance b from the centre of a long thin wire.
The magnetic field Bc is also measure inside the capacitor plates at a distance b from the
axis of the capacitor, where b is less than the radius "a" of the plates. using Maxwell's
equations, show that Bw and Bc change with time in the same way.
Explain qualitatively why this is so.
Basically I get the Bw to B=u0*I(t)/(2*pi*b), I get Bc as uo*I(t)*b/(2*pi*R^2)
But Im stuck on what to do next
