What are Gauss Theorem and Loop Theorem of Steady Magnetic Field? They reflect the properties of stable magnetic fields.

Gauss theorem of magnetic field reflects that the essence of magnetic field is passive field, and Ampere loop theorem reflects that the essence of magnetic field is rotating field (vortex field or non-conservative force field), which can explain that electrostatic field is active field.

Gauss theorem is that the total magnetic flux passing through any closed surface must be zero; The loop theorem is that in the steady current magnetic field in vacuum, the line integral of magnetic induction intensity B along any closed curve L is equal to μ0 times of the algebraic sum of all current intensities passing through this closed curve. Gauss theorem reflects that the steady magnetic field is an active field, and the loop theorem shows that the steady magnetic field is a non-conservative force.

Active areas. Gauss theorem shows that electric field lines can only start with positive charge (or infinity) and end with negative charge (or infinity), that is, electrostatic field is an active field.
