A wire carrying current I has the shape as shown in adjoining figure. Linear parts of the wire are very long and parallel to X-axis while semicircular portion of radius R is lying in Y−Z plane. Magnetic field at point O is

respectively. Point 'I' 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 Two identical long conducting wires AOB and COD are placed at right angle to each other with one above other such that '0' is their common point for the two. The wires carry I1​ and I2​ currents
