The magnetic field in a charging capacitor 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.
