Given by the double integral of a density vector field dotted to a normal vector of a surface, the divergence theorem has this equal to a volume integral while Stoke's theorem equates it with a line integral.
For the Poynting vector, this quantity gives the electromagnetic power. Given by the double integral of a density vector field dotted to a normal vector of a surface, the divergence theorem has this equal to a volume integral while Stoke's theorem equates it with a line integral. For a closed surface, the total amount of one form of this equal to zero and the negative time change in that form of this quantity is equal to the emf. The (*) magnetic and electric forms of this quantity are essential in Faraday's law and both Gauss' laws. For 10 points, name this quantity, which in electromagnetism is thought of as the total number of field lines that pass through a given region.
For the Poynting vector, this quantity gives the electromagnetic power.
