Link between magnet field from a wire and inside a capactior

  1. May 10, 2010 #1
    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.




    Maxwell's equation



    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
