Two infinitely long conductors carrying equal currents are shaped as shown. The short sections are all of equal lengths. The point P is located symmetrically with respect to the two conductors. The magnetic field at P due to any one conductor is B. The total field at P is (a) zero (b) B (c) √2B (d) 2B |

Answer» Correct Answer is: (a) zero The sections of the conductors on either side of P form pairs which produce equal and opposite magnetic fields at P. |
