Abstract: The electromagnetic field from a charging circular parallel plate capacitor is numerically studied by using the Mathematica. The spatial distributions of the electric potential and the electric field intensity as well as the magnetic induction intensity are given. The edge effect of the electromagnetic field is discussed.

Key words: charging circular parallel plate capacitor, plate current, displacement current, electromagnetic field, edge effect, numerical analysis
