    Relative permeability of iron is 5500, then its magnetic susceptibility will be          [KCET 2000; Kerala PMT 2004]

    A)            5500 ´ 107                              

    B)            5500 ´ 10?7

    C)            5501                                         

    D)            5499

    Correct Answer: D

    Solution :

               \[{{\chi }_{m}}=\left( {{\mu }_{r}}-1 \right)\Rightarrow {{\chi }_{m}}=\left( 5500-1 \right)=5499\]
