• Electromagnetic Field Equations

However, we often express the theory in terms
of potentials.

1 Electrostatic Scalar Potential

• Electrostatic Field Equations

For electrostatic irrotational, we can express E
in term of the gradient of a scalar field.
Such a scalar field is called electrostatic
scalar potential.

2 Magnetostatic Vector Potential

• Magnetostatic Field Equations

For no divergence of magnetic field, we can
express B in term of the coul of a vector field.
Such a vector field is called magnetostatic
vector potential.
