Lorentz Force Calculator

Find the magnetic force on a moving charge.

Charge (C)

Velocity

Magnetic field (T)

Angle to field (°)

Calculated Output

Magnetic force (N) 0.0005

Formula: F = q·v·B·sinθ

Step-by-Step Breakdown

1. Values used:

2. Charge = 0 C

3. Velocity = 1,000

4. Magnetic field = 0.5 T

5. Angle to field = 90 °

7. Magnetic force = Charge x Velocity x Magnetic field = 0 x 1,000 x 0.5 = 0.0005N

The math behind it

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

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

What if motion is along the field?

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