How can I display Laplaces force density in magnetic applications?

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:
