There long straight wires A, B and C are carrying current as shown figure. Then the resultant force on B is directed 

                          

(a) Towards A

(b) Towards C

(c) Perpendicular to the plane of paper and outward

(d) Perpendicular to the plane of paper and inward

(b) Fi1i2, so force on B due to C will be greater than that due A. Hence net force on B acts towards C.
