Note: Consider the direction of the current flow shown in each side of the square as positive value of current. If the current value given in the question happens to have negative sign, then consider the current is flowing opposite to the direction shown in the figure. c) In the figure, we see a current carrying square loop. Consider each wire making up the square loop, an infinite current carrying wire. The same current, say, flows through all the sides of the square loop. Each side contributes to the total magnetic field at point P. If the magnetic field due to a side at P is B . Express the total magnetic field at point P, Btotal (due to all the four sides of the square loop), in terms of the magnetic field due to a side at P, B . Hint: It's a conceptual question. No explicit expression of B¡ is required here. You just need to express Btotal in terms of B . d) If each side of the square loop carries a current = 350 mA and the side length is L= 6 cm, then find the magnitude of Btotat at P.
