Magnetic susceptibility ( ) is related to magnetic relative permeability ( _r ) by the relation

Options

  1. A= 1 / ( _r - 1)
  2. B= _r + 1
  3. C= _r - 1
  4. D1 / ( _r + 1)

Correct answer

C. = _r - 1

Step-by-step solution

The magnetic permeability of a material is given by = ₀ (1 + ) , where is the magnetic susceptibility. The relative magnetic permeability is defined as _r = ₀ . Substituting this into the first equation gives _r = 1 + . Rearranging the terms, we get = _r - 1 . Answer: = _r - 1
