AIPMT | 2014Magnetic field due to currentHard
Question
Two identical long conducting wires AOB and COD are placed at right angle to each other, with one above other such that O is their common point for the two. The wires carry I1 and I2 currents, respectively. Point P is lying at distance d from O along a direction perpendicular to the plane containing the wires. The magnetic field at the point P will be
Options
A.
B.
(I1 + I2)
(I1 + I2)C.(i12 - i22)
(i12 - i22)D.(I12 - I22)1/2
(I12 - I22)1/2
