A parallel-plate capacitor is charged until it carries charge + q + q on one plate and charge - q - q on the other plate. The capacitor is then disconnected from the power supply and isolated. What is the direction of the magnetic field that surrounds the charged capacitor? The magnetic field is directed counterclockwise as viewed from the plate with positive charge + q + q toward the plate with negative charge - q - q. There is no magnetic field. The magnetic field is directed counterclockwise as viewed from the plate with negative charge - q - q toward the plate with positive charge + q + q. The magnetic field is directed toward the plate with positive charge + q + q inside the capacitor and toward the plate with negative charge - q - q outside of the capacitor. The magnetic field is directed toward the plate with negative charge - q - q inside the capacitor and toward the plate with positive charge + q + q outside of the capacitor.

There is no magnetic field.

Explanation:

Since th capacitor is charged and isolated, magnetic field doesn't exist.

For magnetic field to exist, there must be flow of charge.
