Lorentz Force Calculation

Output: Press calculate

Formula:F = q(v × B)

Introduction to Lorentz Force Calculator

The Lorentz force is the force on a point charge due to electromagnetic fields. The formula for calculating the Lorentz force F involves the charge q, the velocity of the charge v, and the magnetic field B. The force is given by the product of these quantities, assuming the velocity and magnetic field are perpendicular to each other. This simplifies the cross product into a multiplication for this calculator.

Parameter usage:

Example valid values:


Data validation

Charge, velocity, and magnetic field should be non-zero for meaningful results. Negative values represent direction, but are mathematically valid.


This calculator is designed to provide the Lorentz force acting on a charge moving in a uniform magnetic field, assuming a perpendicular orientation between the charge’s velocity and the magnetic field.
