The definition of magnetic flux linkage is written below with two terms missing.
"The magnetic flux linkage through a coil of N N\,N turns is defined as the product of the number of turns and the magnetic [Term 1] through each turn. By Faraday's law of electromagnetic induction, the magnitude of the induced electromotive force in a coil is equal to the rate of change of magnetic flux linkage, which leads to the alternative SI unit of [Term 2] for magnetic flux linkage."
What are the two missing terms?
Term 1: flux density; Term 2: Vs−1\text{V}\text{s}^{-1}Vs−1
Term 1: flux; Term 2: Vs−1\text{V}\text{s}^{-1}Vs−1
Term 1: flux density; Term 2: Vs\text{V}\text{s}Vs
Term 1: flux; Term 2: Vs\text{V}\text{s}Vs
