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

Step-by-step solution

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