Q: Is there a magnetic field around a fully charged capacitor?

GRANZERI know that a magnetic field exists when a capacitor is in the process of charging/discharging: (a) But what if the Capacitor is fully charged? Will the magnetic field still persist? something like: If there is no magnetic field around an electrostatic field, which of the max law prevents this?...
