Lorentz Force Calculator

Find the magnetic force on a moving charge.

Magnetic force (N) 0.0005

Formula: F = q·v·B·sinθ

Step-by-step with your numbers:
1. Values used:
2. Charge = 0 C
3. Velocity = 1,000
4. Magnetic field = 0.5 T
5. Angle to field = 90 °
6.
7. Magnetic force = Charge x Velocity x Magnetic field = 0 x 1,000 x 0.5 = 0.0005N
Did we solve your problem today?

The Lorentz force deflects charges moving through a magnetic field.

The math behind it

The magnetic part is F = q·v·B·sinθ, greatest when motion is perpendicular to the field (θ = 90°).

Worked example

1 µC at 1000 m/s across 0.5 T → 5 × 10⁻⁴ N.

FAQ

What if motion is along the field?

sin 0° = 0, so there is no magnetic force.
