Intensity of magnetisation I=(M/V)=(M/ text mass/density ) Given mass =1 g=10-3 kg and density =5 g / cm 3=(5 × 10-3 kg /(10-2)3 m 3) =5 × 103 kg / m 3 Hence, I=(6 × 10-7 × 5 × 103/10-3) =3 A / m

Q. The magnetic moment produced in a substance of $1 g$ is $6 \times 1 0^{- 7} A^{-} m^{2}$ . If its density is $5 g / c m^{3}$ , then the intensity of magnetization in $A / m$ will be

$8.3 \times 1 0^{6}$

$3.0$

$1.2 \times 1 0^{- 7}$

$3 \times 1 0^{- 6}$

Q. The magnetic moment produced in a substance of 1g is 6×10−7A−m2. If its density is 5g/cm3, then the intensity of magnetization in A/m will be
