# 7.17.1.29.6. Lorentz

Syntax

  Source For Momentum ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} MeshPartIdentifier = Lorentz [Magnetic_Field = magnetic_field]

Summary

  Lorentz source due to either an externally applied or calculated magnetic field J X B. J is the current from the current equation. B is either an imported vector field whose name is given by MAGNETIC_FIELD or the magnetic field calculated by Aria
