The force experienced by a charged particle moving in an electromagnetic field.
Charged particles move in circular paths in uniform magnetic fields.
Enter the charge value, velocity, magnetic field strength, and the angle between velocity and field vectors. Click Calculate to find the magnetic force on the moving charge.
An electron (q=1.6×10⁻¹⁹C) moving at 10⁶ m/s perpendicular to a 0.1T field: F = 1.6×10⁻¹⁹ × 10⁶ × 0.1 = 1.6×10⁻¹⁴ N.
A: The Lorentz Force is the combined electric and magnetic force on a charged particle: F = q(E + v × B).
A: Point fingers in the direction of velocity, curl toward the magnetic field — your thumb points in the force direction (for positive charges).
A: The magnetic force is always perpendicular to velocity, so it changes direction but not speed — thus doing no work.
A: Electric motors, cathode ray tubes, mass spectrometers, particle accelerators, and MRI machines all use Lorentz Force.
