Q4. A small magnetic dipole is kept at the origin in the x-y plane. One wire L is located at z=-a in the x-z plane with a current I flowing in the positive r direction. Another wire L is at z = +a in y-z plane with the same current I as in L, flowing in the positive y-direction. The angle ó made by the magnetic dipole with respect to the positive X-axis is (a) 225 (b) 120 (c) 45 (d) 270
