Question

Match the following.

	List I		List II
A	Magnetic field intensity	E	$Wb/m$
B	Magnetic flux	F	$Wb/m^2$
C	Magnetic potential	G	$Wb$
D	Magnetic inductor	H	$A{m}^{-1}$

• A. $A-H,B-G,C-E,D-F$
• B. $A-G,B-H,C-E,D-F$
• C. $A-E,B-H,C-G,D-F$
• D. $A-F,B-G,C-H,D-F$

Answer 1

Answer: (A)

$A-H,B-G,C-E,D-F$

(A) The magnetic field can be visualized as magnetic field lines. The field intensity corresponds to the density of the field lines. It is measured in Amperes per meter - $A{m}^{-1}$ (H)
(B) The total number of magnetic field lines penetrating an area is called the magnetic flux with unit tesla meter squared - $T{m}^2$ or Weber Wb (G)
(C) Magnetic potential has unit $WB/m$ (E)
(D) Magnetic induction (also known as magnetic flux density) describes a magnetic field (a vector) at every point in space with unit $Wb/m^2$ (F)
