The Laplace’s electromagnetic force is the force exerted on a conducting coil placed in a magnetic field. The force exerted on a conductor can be computed using Laplace’s law:

B is the magnetic flux density in which the conductor is placed

J is the current density in the conductor

In Flux, the density of Laplace’s force could be displayed by means of arrows of:

• DFLaplace/DV (Mean component)
• DFLaplace/DV 2w (Pulsating component)
• PVec(J,B) = DFLaplace/DV + DFLaplace/DV 2w
