At temperature

{T_1},

the magnetic susceptibility of a diamagnetic material is

{\chi _1}

and at temperature

{T_2},

it is

{\chi _2}.

Then

View answer and explanation

Correct option: D

{\chi _1} = {\chi _2}

Option D (

\chi_1 = \chi_2

) is correct because the magnetic susceptibility of a diamagnetic material is independent of temperature.

Curie temperature is the one above which A vibration magnetometer consists of two identical bar magnets placed one over the other such that they are perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field is

{2^{5/4}}

s. One of the magnets is removed and if the other magnet oscillates in the same field , then the time period in second is The relative permeability of a substance

X

is slightly less than unity and that of substance

Y

is slightly more than unity, then A bar magnet is equivalent to If the magnetic dipole moment of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are denoted by
