The magnetic susceptibility of a material of a rod is 349 and permeability of vacuum ₀ is 4 10⁻⁷ SI units. Absolute permeability of the material of the rod in SI units
Options
- A4200 10⁻⁷
- B4600 10⁻⁷
- C4400 10⁻⁷
- D4800 10⁻⁷
Correct answer
C. 4400 10⁻⁷
Step-by-step solution
Given: ₀=4 10⁻⁷ Hm ⁻¹ Magnetic susceptibility of a material of rod: _ m =349 absolute permeability of material of rod: = ₀ (1+ _ m ) Or, =4 10⁻⁷(1+349)=43982.3 10⁻⁴ Hm ⁻¹ 4400 10⁻⁷ Hm ⁻¹
