The magnetic moment product in a sample of 2 gram is 8 10⁻⁷ Am ^2 . If its density is 4 ~g / cm ^3 then the magnetization of the sample in Am ⁻¹ is

Step-by-step solution

Volume of the sample V= mass density = 2 4 ~cm ^3=0.5 10⁻⁶ ~m ^3 Magnetization = Megnetic moment Volume = 8 x 10⁻⁷ 0.5 10⁻⁶ ~A / m =1.6 ~A / m
