The relative permeability of iron is 6000 . Its magnetic susceptibility is

Options

  1. A5999
  2. B6001
  3. C6000 10⁻⁷
  4. D6000 10⁷

Correct answer

A. 5999

Step-by-step solution

The relationship between relative permeability _ r and magnetic susceptibility is given by the formula: _ r = 1 + Given that the relative permeability of iron is _ r = 6000 , we substitute this value into the equation: 6000 = 1 + Solving for : = 6000 - 1 = 5999 Answer: 5999
