Review • Electromagnetic Field Equations However, we often express the theory in terms of potentials. Classical Electrodynamics
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. Classical Electrodynamics
Electrostatic Potential Equation Coulomb’s solution Classical Electrodynamics
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. Classical Electrodynamics
