Larmor Radius Calculator: Predict Charged Particle Motion

Calculate Larmor Radius

Easily calculate the Larmor radius, also known as the gyroradius, for charged particles in a uniform magnetic field. This intuitive online tool is crucial for understanding particle behavior in plasma physics, fusion energy, and space weather studies. Input particle mass, velocity, charge, and magnetic field strength for instant, precise results.

Formula:

The Larmor radius (rL) is calculated using the formula:

rL = (m × v) / (q × B)

  • rL = Larmor Radius (meters)
  • m = Mass of the charged particle (kilograms, kg)
  • v = Velocity of the charged particle (meters per second, m/s)
  • q = Magnitude of the charged particle's charge (Coulombs, C)
  • B = Magnetic field strength (Tesla, T)
