Lorentz force acting on fast-moving charged particles in a bubble chamber.Positive and negative charge trajectories curve in opposite directions. In physics, specifically in electromagnetism, the Lorentz force law is the combination of electric and magnetic force on a point charge due to electromagnetic fields.
The Lorentz self-force derived for non-relativistic velocity approximation , is given in SI units by: = ˙ = ˙ = ˙ or in Gaussian units by = ˙. where is the force, ˙ is the derivative of acceleration, or the third derivative of displacement, also called jerk, μ 0 is the magnetic constant, ε 0 is the electric constant, c is the speed of light in free space, and q is the electric charge of ...
Equation implicitly contains the Lorentz force law and the differential form of Faraday's law of induction. For a static magnetic field, ∂ A / ∂ t {\displaystyle \partial \mathbf {A} /\partial t} vanishes, and the electric field E becomes conservative and is given by −∇ ϕ , so that (D) reduces to
Generally conservative of quantity. [9]: ... Given the fields, the Lorentz force law is the equation of motion for charges in the fields. Maxwell's equations.
The way in which charges and currents (i.e. streams of charges) interact with the electromagnetic field is described by Maxwell's equations [4] and the Lorentz force law. [5] Maxwell's equations detail how the electric field converges towards or diverges away from electric charges, how the magnetic field curls around electrical currents, and ...

The covariant formulation of classical electromagnetism refers to ways of writing the laws of classical electromagnetism (in particular, Maxwell's equations and the Lorentz force) in a form that is manifestly invariant under Lorentz transformations, in the formalism of special relativity using rectilinear inertial coordinate systems. These ...
Faraday's law describes two different phenomena: the motional emf generated by a magnetic force on a moving wire (see Lorentz force), and the transformer emf that is generated by an electric force due to a changing magnetic field (due to the differential form of the Maxwell–Faraday equation).
