An iron rod of susceptibility 599 is subjected to a magnetizing field of \[1200\text{ }A\text{ }{{m}^{1}}\]. |
The permeability of the material of the rod is: |
\[({{\mu }_{0}}=4\pi \times {{10}^{-7}}T\,m\,{{A}^{-1}})\] [NEET 2020] |
A) \[8.0\times {{10}^{5}}\text{ }T\text{ }m\text{ }{{A}^{1}}\]
B) \[2.4\pi \times \text{ }{{10}^{5}}\text{ }T\text{ }m\text{ }{{A}^{1}}\]
C) \[2.4\pi \times {{10}^{7}}\text{ }T\text{ }m\text{ }{{A}^{1}}\]
D) \[2.4\pi \times {{10}^{4}}\text{ }T\text{ }m\text{ }{{A}^{1}}\]
Correct Answer: A
Solution :
[a] |
\[\delta =+25\] |
\[{{B}_{v}}\]\[\to \]vertical downward \[\to \] Northern hemisphere |
A \[\to \] Northern hemisphere |
B \[\to \] Southern hemisphere |
