flux density

• 科学术语，指单位面积上垂直通过的通量（如磁通量或电通量）的多少。

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.

   磁通密度

   • 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.

   电通量密度

   • 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.
