Dimensionless quantities represent special combinations of physical quantities relevant to a physical system, and they often characterize the behavior of that system. From the magnetic Reynolds number to the Cowling number to the Lorentz number, use Wolfram|Alpha to look up definitions and compute values of important dimensionless quantities in electrodynamics.
