P2 8 Only a Sith deals in Magnetohydrodynamics

Abstract

In this paper, we investigate the iconic humming noise produced by the lightsaber from the Star
Wars movie franchise. We apply a magnetohydrodynamic model to investigate the formation of
standing Alfv´en waves within the lightsaber plasma and find that for the fundamental frequency
of these waves to be within the range of human hearing, a lightsaber of magnetic field 1 T would
require a plasma density of 10²⁶ m⁻³
