Three infinite straight wires A, B and C carry currents as shown in figure. The resultant force on wire B is directed (a) towards A (b) towards C (c) perpendicular to the plane of page (d) upwards

Answer: (a). A and B carry current in the same direction (down): A attracts B, force on B towards A. C carries current opposite to B: C repels B, force on B away from C, i.e. towards A. Both forces point towards A. So the answer is (a) towards A.

Force on Current-Carrying Conductors

Three infinite straight wires $A, B$ and C carry currents as shown in figure. The resultant force on wire $B$ is directed

Show answer and solution

Answer: (a)

A and B carry current in the same direction (down): A attracts B, force on B towards A.
C carries current opposite to B: C repels B, force on B away from C, i.e. towards A.
Both forces point towards A.
So the answer is (a) towards A.
