A long wire carrying a steady current is bent into a circular loop of one turn. The magnetic filed at the centre of the loop is B. It is them bent into circular coil of n turns. The magnetic field at the centre of this cold of n turns will be.

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
