The magnetic susceptibility of iron is 5499. The relative permeability of iron will be

Options

  1. A5500 10^7
  2. B5500 10⁻⁷
  3. C5500
  4. D5501

Correct answer

C. 5500

Step-by-step solution

The relationship between magnetic susceptibility ( _m ) and relative permeability ( _r ) is expressed as _r = 1 + _m . Given _m = 5499 for iron, substitution yields _r = 1 + 5499 = 5500 . The relative permeability of iron is therefore 5500 . The correct option is C.
