Question 8

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?

A

Term 1: flux density; Term 2: Vs−1\text{V}\text{s}^{-1}Vs−1

B

Term 1: flux; Term 2: Vs−1\text{V}\text{s}^{-1}Vs−1

C

Term 1: flux density; Term 2: Vs\text{V}\text{s}Vs

D

Term 1: flux; Term 2: Vs\text{V}\text{s}Vs
