Current Attempt in Progress

The induced magnetic field at radial distance $5\mathrm{.}22$ mm from the central axis of a circular parallel$-$plate capacitor is $\backslash (2\mathrm{.}96\backslash$times $10^\{-8\}\backslash$mathrm$\{$~T$\}\backslash ).$ The plates have radius $4\mathrm{.}35$ mm $.$ At what rate is the magnitude of the electric field between the plates changing?
