Electric flux Wikipedia

An electric charge, such as a single electron in space, has an electric field surrounding it. In pictorial form, this electric field is shown as a dot, the charge, radiating "lines of flux". These are called Gauss lines. Note that field lines are a graphic illustration of field strength and direction and have no physical meaning. The density of these lines corresponds to the electric field strength, which could also be called the electric flux density: the number of "lines" per unit area. Electric fl

Magnetic Flux Density: Definition, Formula, Units

网页Magnetic flux density is the measure of the strength of the magnetic field. Currents (and the wires through which they travel) are affected by magnetic fields and impacted by magnetic forces. The magnetic flux density is a vector field that does not exert a force on the direction to which it points but rather in a direction perpendicular to it.
