Magnetic Force on Charge Calculator

Summary

Enter charge, velocity, magnetic field strength, and angle to instantly compute the magnetic force using F = qvB sin(θ).

How it works

1. Enter the electric charge (q) and select its unit (C, mC, µC, nC).
2. Enter the particle velocity (v) and select its unit (m/s, km/s, km/h).
3. Enter the magnetic field strength (B) and select its unit (T or mT).
4. Enter the angle (θ) between the velocity vector and the magnetic field vector in degrees.
5. The magnetic force F = qvB sin(θ) is computed instantly.
6. Use the Reset button to clear all inputs and start a new calculation.

Use cases

• Solve introductory physics problems on charged particles in magnetic fields.
• Verify homework or exam answers for Lorentz force calculations.
• Explore how force varies with the angle between velocity and field.
• Analyze particle motion in cyclotrons, mass spectrometers, and synchrotrons.
• Understand why a charge moving parallel to a field experiences no force.
• Compare magnetic force magnitudes for different charge types and speeds.
