A magnetic needle placed at a distance r from a straight conductor of 8r carrying a current of I shows a deflection of $( theta). What may be the deflection on passing the same current when the conductor is bent in the form of a square and the magnetic needle is placed at a point of intersection of the diagonals of the sqare.
