A bar magnet made of steel has a magnetic moment of 2.5 Am22.5 \mathrm{~Am}^2 and a mass of 6.6×103 kg6.6 \times 10^3 \mathrm{~kg}. If the density of steel is 7.9×109 kg/m37.9 \times 10^9 \mathrm{~kg} / \mathrm{m}^3, find the intensity of magnetization of the magnet.
View answer and explanation
Correct option: A
3.0×106 A/m3.0 \times 10^6 \mathrm{~A} / \mathrm{m}
Option A (3.0×106 A/m3.0 \times 10^6 \mathrm{~A} / \mathrm{m}) is correct because it is calculated by dividing the magnetic moment by the volume of the magnet.
