Hi everyone, I'm doing a problem that involves two circular capacitor plates with radius R connected to wires running current I (as in a circuit), and need to find the magnetic field at three different regions between the two plates as a function of r, radial distance from the center of the two plates.(adsbygoogle = window.adsbygoogle || []).push({});

Using Ampere's Law, ∫B*dl = μ(I +εd[itex]\Psi[/itex]/dt)

where μ and ε are the magnetic constant and electric constant.

B is magnetic field, I is current, and [itex]\Psi[/itex] is flux of electric field (between the two cap. plates, I 'spose).

I figured the best loop to integrate over is a circle (parallel to and in between the two plates).

How will I go about it from here?
