Question

16) The variation of intensity of magnetization I and the applied
magnetic field intensity H for three magnetic material X, Y and Z
are as shown given in the graphs

(i) Identify the materials X, Y and Z ?
(ii) Show variation of susceptibility with temperature X?
(iii) Out of Y and Z which of the material will you prefer for
making transformer core and why?

Dear Student
from formula of I and HI =kH tanθ  where k=2πμ0ntanθ=IHfrom diagram greater the angle for Y than Z and last followed by Xgreater the deflection means its ferromagnetic , followed by paramagnetic at last its is dimagnetic hence Y -- ferromagnetic              Z-- paramagnetic             X-- dimagneticthe variation of sustebility with temperature is inverse material Y is used to mage transformer because it support magnetic flux as it is ferromagnetic in nature
