The magnetic moment produced in a sample of 2 gram is 8 10⁻⁷ , A/m ^2 . If its density is 4 g/cm ^3 then the magnetization of the sample is
Options
- A1.6
- B1.2
- C1.4
- D1.8
Correct answer
A. 1.6
Step-by-step solution
Given, mass of the sample m = 2 g Density of the sample d = 4 g/cm ^3 Volume of the sample V = m d = 2 4 = 0.5 cm ^3 = 0.5 10⁻⁶ m ^3 Magnetic moment M = 8 10⁻⁷ A m ^2 Magnetization I = M V I = 8 10⁻⁷ 0.5 10⁻⁶ = 1.6 A/m Answer: 1.6
