1.	A constant current I flows in a horizontal wire in the plane of the paper from West to East as shown in the figure. The direction of magnetic field at a point will be South to North (1) directly above the wire (2) directly below the wire (3) at a point located in the plane of the paper, on the north side of the wire. (4) at a point located in the plane of the paper, on the south side of the wire.
Answer» (2) directly below the wire Using Maxwell’s right hand thumb rule.
