Magnetic and Electric Potentials
Using the definitions of the potentials,
and the constitutive relation B = μ0(H + M), Ampère’s law can be rewritten as
(2-20)
The equation of continuity, which is obtained by taking the divergence of the above equation, adds the following equation:
(2-21)
Equation 2-20 and Equation 2-21 form a system of equations for the two potentials A and V.
