The magnetic susceptibility of the material of a rod is 599. The absolute permeability of the material of the rod will be [ ₀=4 10⁻⁷ . SI unit ] .
Options
- A2 10⁻⁴
- B2.4 10⁻⁴
- C4 10⁻⁴
- D4.8 10⁻⁴
Correct answer
B. 2.4 10⁻⁴
Step-by-step solution
We know, = _ r ₀=(1+ ) ... _ r is relative permeability Substituting the given values into the above equation, we get aligned _ r & =(1+ ) _ o =(1+599) (4 10⁻⁷ ) & =2.4 10⁻⁴ aligned
