विकल्प

• 0.6

• `1/6`

• 6

• 60

Answer 1

The magnetic moment produced in a substance of mass 5 gram is 6 x 10^-7 Am² If its density is 5 g/cm³, then intensity of magnetization in `"A"/"m"` will be 0.6.

Explanation:

Mass = 5 g, density = 5 g/cm³

`"Volume V" = "mass"/"density" = (5"g")/(5"g"//"cm"^3) = 1  "cm"^3 = 10^-6  "m"^3`

`"magnetization" = "magnetic moment"/"volume"`

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

`= 0.6  "A/m"`
