The magnetic moment produced in a sample of 2 gram is $8 \times 1 0^{- 7} A/m^{2}$ . If its density is $4 g/cm^{3}$ then the magnetization of the sample is

Options:

Answer:

Solution:

Given, mass of the sample $m = 2 g$

Density of the sample $d = 4 g/cm^{3}$

Volume of the sample $V = \frac{m}{d} = \frac{2}{4} = 0.5 cm^{3} = 0.5 \times 1 0^{- 6} m^{3}$

Magnetic moment $M = 8 \times 1 0^{- 7} A m^{2}$

Magnetization $I = \frac{M}{V}$

$I = \frac{8 \times 1 0 ^{- 7}}{0.5 \times 1 0 ^{- 6}} = 1.6 A/m$

Answer: $1.6$
