Question

The magnetic field between the plates of a capacitor when r greater than R is given by

  1. fraction numerator mu subscript 0 I subscript D over denominator 2 pi R squared end fraction    
  2. fraction numerator mu subscript 0 end subscript I subscript D end subscript over denominator 2 pi R end fraction    
  3. fraction numerator mu subscript 0 end subscript I subscript D end subscript over denominator 2 pi r end fraction    
  4. zero    

The correct answer is: fraction numerator mu subscript 0 end subscript I subscript D end subscript over denominator 2 pi r end fraction
