A magnetic compass needle is placed in the plane of paper near point A as shown in Figure. In which plane should a straight current-carrying conductor be placed so that it passes through A and there is no change in the deflection of the compass? Under what condition is the deflection maximum and why?

  • In the plane of the paper itself. The axis of the compass is vertical and the field due to the conductor is also vertical. 
  • It could result in a dip of compass needle which is not possible in this case (dips result only if axis of compass is horizontal). 
  • The deflection is maximum when the conductor through A is perpendicular to the plane of paper and the field due to it is maximum in the plane of the paper
