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. 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?
