Aparallel-plate capacitor 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 μ0 and given quantities.

1. The problem statement, all variables and given/known data 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. 2. Relevant equations When a capacitor is charged, the electric field E, and hence the electric flux Φ, between the plates changes. This change in flux induces a magnetic field, according to Ampère's law as extended by Maxwell: ∮B⃗ ⋅dl⃗ =μ0(I+ϵ0dΦdt). You will calculate this magnetic field in the space between capacitor plates, where the electric flux changes but the conduction current I is zero.

answer; i believe the correct answer is (40,000 j) good luck
