Electrodynamics/Notation

This book uses a consistent notation for its equations. We will describe the symbols we use here, as well as other ways that those concepts are notated in other books. : Gradient operator 2: Laplacian operator : d'Alembertian operator A: Area A: Magnetic potential field B: Magnetic field c: Speed of light D: E: Electric Field Fe: Electric force vector Fm: Magnetic force vector F: Field Tensor G: Magnetic Field Tensor H: I: Current, in amperes j: Electric current j: Electric current density k: Coulomb's Constant K: Magnetic Constant l: length L: Lorentz transformation matrix M: Magnetization field n: Normal vector φ: Electric potential function r: Scalar distance r, θ, z: Cylindrical coordinates r, θ, ρ: Spherical coordinates r: Distance vector R: Rotation matrix σ: Charge density TE: Electric stress tensor TM: Magnetic stress tensor V: Volume x, y, z: Cartesian Coordinates
