SpletMaxwell’s equations are relativistic invariant in the parlance of special relativity [1]. In fact, Einstein was motivated with the theory of special relativity in 1905 by Maxwell’s equations [2]. These equations look the same, irrespective of what inertial reference frame one is in. Maxwell’s equations are valid in the quantum regime, as ...

Did you know?
Maxwell's equations are partial differential equations that relate the electric and magnetic fields to each other and to the electric charges and currents. Often, the charges and currents are themselves dependent on the electric and magnetic fields via the Lorentz force equation and the constitutive relations. … Prikaži več Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, … Prikaži več In the electric and magnetic field formulation there are four equations that determine the fields for given charge and current distribution. A separate law of nature, … Prikaži več In a region with no charges (ρ = 0) and no currents (J = 0), such as in a vacuum, Maxwell's equations reduce to: Taking the curl (∇×) of the curl equations, and using the curl of the curl identity we obtain The quantity Prikaži več The Maxwell equations can also be formulated on a spacetime-like Minkowski space where space and time are treated on equal footing. The … Prikaži več Gauss's law Gauss's law describes the relationship between a static electric field and electric charges: … Prikaži več The invariance of charge can be derived as a corollary of Maxwell's equations. The left-hand side of the modified Ampere's law has zero divergence by the div–curl identity. Expanding the divergence of the right-hand side, interchanging derivatives, and applying … Prikaži več The above equations are the microscopic version of Maxwell's equations, expressing the electric and the magnetic fields in terms of the (possibly atomic-level) charges and … Prikaži več SpletMaxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits.The equations provide a mathematical model for electric, optical, and radio technologies, such as power …
