Magnetic Force Calculator – F = qvB sin(θ)

Calculate magnetic force on a moving charge using F = qvB sin(θ).

How It Works

Enter charge (C), velocity (m/s), magnetic field strength B (Tesla), and the angle between velocity and field. The calculator returns the Lorentz magnetic force in Newtons.

Formula

F = q × v × B × sin(θ)

Frequently Asked Questions

What is the Lorentz force?

The Lorentz force is the force on a charged particle moving through a magnetic field: F = qvB sin(θ). Maximum force occurs when velocity is perpendicular to the field (θ = 90°).

When is magnetic force zero?

When the charged particle moves parallel to the magnetic field (θ = 0° or 180°), sin(θ) = 0 and there is no magnetic force.
