| Two electrode plates are modeled and arranged in parallel, which has the
basic structure of a capacitor. When the different electric potential is
constantly applied to each plate, electric charge stored in the electrode
plates varies with the relative permittivity of the dielectric material
between the electrode plates. This note presents the use of magnetic field
analysis to obtain the electric charges of both the air and the high permittivity
material when they are placed between the electrode plates, and calculate
the capacitance. |
