A parallel-plate capacitor of capacitance C with circular plates is charged by a constant current I. The radius a of the plates is much larger than the distance d between them, so fringing effects are negligible. Calculate B(r), the magnitude of the magnetic field inside the capacitor as a function of distance from the axis joining the center points of the circular plates.
Express your answer in terms of mu_0 and given quantities.
according to Ampère's law as extended by Maxwell:
[tex]
\oint \vec{B} \cdot d\vec{l}= \mu_0\left(I+ \epsilon_0 \frac{d\Phi}{dt}\right).
[/tex]
what should i do then?
please advise...
