The Field Concept

[latexpage]A field describes how quantities are distributed in space Two types exist: Scalar fields or vector fields; As in this example, electric scalar potential $V$ and electrostatic vector field $E$, respectively Electromagnetic fields are postulated to exist via observable phenomena, e.g., via the Lorentz Force: \[F=q(E + v * B)\] Plot notables: Light colors: “high…
