Two materials X and Y are magnetised, whose intensity of magnetisation are 500 A `m^(-1)` and 2000 `A m^(-1)`, respectively. If the magnetising field is 1000 A `m. then which one among these materials can be easily magnetized ?

Explanation

The susceptibility of material X is `X_(m) x = |(vec(M))/(vec(H))| = (500)/(1000) = 0.5 `
The susceptibility of material Y is `X_(m) Y = |(vec(M))/(vec(H))| = (2000)/(1000) = 2`
Since, susceptibility of material Y is greater than of material X. material Y can be easily magnetized than X.
