Please addA circular loop of radius `R` carries current `I_2` in a clockwise direction as shown in figure. The centre of the loop is a distance `D` above a long, straight wire. What are the magnitude and direction of the current `I_1` in the wire if the magnetic field at the centre of loop is zero?
