Question 13: Magnetism and Matter

Question

Match List - I with List - II.

List - I
List - II

(A) Magnetic induction
(I) Ampere meter2

(B) Magnetic intensity
(II) Weber

(C) Magnetic flux
(III) Gauss

(D) Magnetic moment
(IV) Ampere meter

Choose the correct answer from the options given below:

Accepted Answer

(A) The unit "gauss" is used to measure magnetic induction, also known as magnetic flux density, within the CGS system of units.
$$B = {\phi  \over A} = {{\max well} \over {c{m^2}}} = gauss\,(CGS)$$
(B) Magnetic intensity (H) is defined as the product of the number of turns per unit length in a coil (n) and the current that it carries (I).
i.e. $$H = nI = {N \over L}I$$
Unit : A/m or Am$^{-1}$
(C) Magnetic flux, $$\phi  = BA$$
unit : weber
(D) Magnetic moment (M) : magnetic moment of a current loop, $$M = NIA$$
where, N = number of turns
I = current
A = Area
So, unit = Am$^2$
Hence, option A is correct.
