Question

The magnetic susceptibility of a paramagnetic material at ${73}^o$C is $0.0075$. Then its value at ${173}^o$C will be

• A. $0.0058$
• B. $0.0075$
• C. $0.0045$
• D. $0.0015$

Answer 1

The correct option is A $0.0058$

The magnetic Susceptibility of a material varies inversely with temperature.
Thus, $M_1{T}_1=M_2{T}_2$
To find $T_2$ we substitute the values, and obtain it equal to,
$=0.0058$
