flux density

• Terme scientifique désignant la quantité d'une grandeur physique (telle que le flux magnétique ou le flux électrique) traversant une surface unité perpendiculaire à la direction du flux.

A scientific term referring to the amount of a physical quantity (such as magnetic flux or electric flux) passing through a unit area perpendicular to the direction of flow.

1. Magnetic flux densityC2formal

   A measure of the amount of magnetic flux passing through a unit area perpendicular to the direction of the magnetic field.

   densité de flux magnétique

   • The magnetic flux density inside the solenoid was measured in teslas.
   • Engineers calculated the flux density to design the transformer core.
   • High flux density can cause saturation in magnetic materials.

2. Electric flux densityC2formal

   A measure of the electric field strength in a dielectric material, representing the amount of electric flux per unit area.

   densité de flux électrique

   • The electric flux density in the capacitor is proportional to the applied voltage.
   • Maxwell's equations relate electric flux density to charge density.
   • The flux density vector is used to analyze field patterns in antennas.
