Column II |
A. Point P is situated midway between the wires above.
B. Point P is situated at the mid point of the line joining the centres of the circular wires, which have same radii.

(i) The magnetic fields B at P due to the current in the wires are in the same direction.
(ii) The magnetic fields B at P due to the current in the wires are in the opposite directions.
(iii) Magnetic field at P is zero. |
