Question

The magnetic moment produced in a sample of 2 gram is 8 x 10^-7 A/m². lf its density is 4g/cm³, then the magnetization of the sample is ____________.

Options

• 1.6

• 1.8

• 1.4

• 1.2

Answer 1

The magnetic moment produced in a sample of 2 gram is 8 x 10^-7 A/m². lf its density is 4g/cm³, then the magnetization of the sample is 1.6.

Explanation:

`"Volume of the sample V" = "mass"/"density"`

`= 2/4`

` = 0.5  "cm"^3`

`= 0.5 xx 10^-6 "m"^3`

`"Magnetization" = "Magnetic moment"/"Volume"`

`= (8 xx 10^-7)/(0.5 xx 10^-6)`

`= 1.6  "A"//"m"`
