Calculate Lienard-Wiechert Potential

Enter the charge of the particle in microcoulombs (1 µC = 10⁻⁶ C).
Distance from observation point to charge's retarded position in meters.
Velocity of the source charge at the retarded time in meters per second.
Angle between velocity vector and position vector (0 to 180 degrees).
Constant speed of light in vacuum.
Constant permittivity of free space.

Unravel the complexities of relativistic electromagnetism with our Lienard-Wiechert Electric Potential Calculator. Accurately compute the electric potential generated by a moving point charge, considering the crucial concept of retarded time. Ideal for students and professionals in physics and engineering seeking to understand the Lienard-Wiechert potentials.

Formula:

The Lienard-Wiechert electric potential (V) at an observation point and time due to a moving charge (q) is given by:

V = (1 / 4πε₀) × [ q / (Rret × (1 - (vs × cos(θ)) / c)) ]

  • V: Electric Potential (Volts)
  • q: Charge of the particle (Coulombs)
  • ε₀: Permittivity of free space (8.854 × 10-12 F/m)
  • Rret: Retarded distance, the distance from the observation point to the charge's position at the retarded time (meters)
  • vs: Velocity of the source charge at the retarded time (m/s)
  • θ: Angle between the velocity vector (vs) and the vector from the retarded position to the observation point (degrees)
  • c: Speed of light in vacuum (299,792,458 m/s)
