1. :: Lasers emit light-electromagnetic waves-and an electromagnetic wave does not carry or move charge . 2. To calculate this, consider the electrical currents in space generated by a moving charge 3. Moving charge induces a magnetic field, which stores energy.4. Electric charge particles in motion produce magnetic fields that generate forces on othe moving charges . 5. Such a moving charge induces a magnetic field. 6. The questioner asked about a moving charge . 7. Following is the formula for moving charge ; for the forces on an intrinsic dipole, see magnetic dipole. 8. All moving charged particles produce magnetic fields. 9. Those fields can then affect the force on, and can then move other slowly moving charged particles. 10. Electrostatics deals with electric charges at rest, electrodynamics with moving charges , and magnetostatics with magnetic poles at rest.
