A capacitor is charging in a simple RC circuit with a dc battery.Which one of the following statements about this capacitor is accurate?
A) There is a magnetic field between the capacitor plates because charge travels between the plates by jumping from one plate to the other.
B) There is no magnetic field between the capacitor plates because no charge travels between the plates.
C) There is a magnetic field between the capacitor plates, even though no charge travels between them, because the magnetic flux between the plates is changing.
D) There is a magnetic field between the capacitor plates, even though no charge travels between them, because the electric flux between the plates is changing.
E) The magnetic field between the capacitor plates is increasing with time because the charge on the plates is increasing.

When a capacitor is charging, an electric current flows in the circuit, which leads to a changing electric flux between the plates. According to Maxwell's equations, a changing electric flux induces a magnetic field, even though no charge actually travels through the vacuum between the capacitor plates.
