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
(10-7)
The equation of continuity, which is obtained by taking the divergence of the above equation, adds the following equation:
(10-8)
Equation 10-7 and Equation 10-8 form a system of equations for the two potentials A and V.
