Answer 2

Given data : The magnetic moment of magnet of dimensions 5 cm x 2.5 cm x 1.25 cm is 3 Am².

To find : Calculate the intensity of magnetization

Solution : Here,

• Magnetic moment = 3 Am²
• Volume = 5 cm * 2.5 cm * 1.25 cm

Now,

➜ Volume = {5 * 2.5 * 1.25} cm³

➜ Volume = {5/100 * 2.5/100 * 1.25/100} m³

➜ Volume = {12.5/10000 * 1.25/100} m³

➜ Volume = {15.625/1000000} m³

➜ Volume = {15.625/10⁶} m³

By fomula of intensity of magnetization;

➜ I = M/V

where,

• I is intensity of magnetization,
• M is magnetic moment
• V is volume

➜ I = M/V

➜ I = 3/(15.625/10⁶)

➜ I = (3 * 10⁶)/15.625

➜ I = 192000

➜ I = 192 * 10³ A/m

Answer : Hence, the intensity of magnetization is 192 * 10³ A/m. {192000 A/m}
