Question

The mutual inductance between the rectangular loop and the long straight wire as shown in figure is M.

  1. M = Zero    
  2. M equals fraction numerator mu subscript 0 end subscript a over denominator 2 pi end fraction l n invisible function application open parentheses 1 plus fraction numerator c over denominator b end fraction close parentheses    
  3. M equals fraction numerator mu subscript 0 end subscript b over denominator 2 pi end fraction l n invisible function application open parentheses fraction numerator a plus c over denominator b end fraction close parentheses    
  4. M equals fraction numerator mu subscript 0 end subscript a over denominator 2 pi end fraction l n invisible function application open parentheses 1 plus fraction numerator b over denominator c end fraction close parentheses    

The correct answer is: M equals fraction numerator mu subscript 0 end subscript a over denominator 2 pi end fraction l n invisible function application open parentheses 1 plus fraction numerator b over denominator c end fraction close parentheses
