# Lorentz Force

on . Posted in Electromagnetism

Lorentz force, abbreviated as F, is the force experienced by a charged particle moving through an electromagnetic field.  The direction of the Lorentz force is perpendicular to both the velocity of the charged particle and the direction of the magnetic field.

This force is fundamental in understanding the motion of charged particles in various physical systems, such as electrons in electric circuits, charged particles in magnetic fields, and the behavior of charged particles in plasmas.  The Lorentz force is a basic concept in classical electromagnetism and is also incorporated into the equations of motion in electromagnetic theory.

### Lorentz Force formula

$$F = Q \; ( E \; v \; B )$$     (Lorentz Force)

$$Q = F \;/\; E \; v \; B$$

$$E = F \;/\; Q \; v \; B$$

$$v = F \;/\; Q \; E \; B$$

$$B = F \;/\; Q \; E \; v$$

Symbol English Metric
$$F$$ = Lorentz force $$T$$  $$kg\;/\;s^2-A$$
$$Q$$ = electric charge  $$C$$ $$A-s$$
$$E$$ = electric field $$V\;/\;ft$$   $$V\;/\;m$$
$$v$$ = velocity of charge particle $$ft\;/\;sec$$   $$m\;/\;s$$
$$B$$ = magnetic field $$T$$  $$kg\;/\;s^2-A$$
